Find the LCM & HCF for the given numbers.

Lati wa LCM (Least Common Multiple) ati HCF (Highest Common Factor) fun awọn nọmba wọnyi, a yoo lo ọna ipin nọmba akọkọ (prime factorization). 1. Fun awọn nọmba 63, 42, 21 Step 1: Wa awọn ipin nọmba akọkọ fun nọmba kọọkan. 63 &= 3 × 3 × 7 = 3^2 × 7 \\ 42 &= 2 × 3 × 7 \\ 21 &= 3 × 7 Step 2: Wa HCF (Highest Common Factor). Eyi ni ọja ti awọn ipin nọmba akọkọ ti o wọpọ pẹlu agbara ti o kere julọ. HCF = 3^1 × 7^1 = 3 × 7 = 21 Step 3: Wa LCM (Least Common Multiple). Eyi ni ọja ti gbogbo awọn ipin nọmba akọkọ ti o wa ninu awọn nọmba pẹlu agbara ti o ga julọ. LCM = 2^1 × 3^2 × 7^1 = 2 × 9 × 7 = 126 2. Fun awọn nọmba 144, 216, 360 Step 1: Wa awọn ipin nọmba akọkọ fun nọmba kọọkan. 144 &= 2 × 2 × 2 × 2 × 3 × 3 = 2^4 × 3^2 \\ 216 &= 2 × 2 × 2 × 3 × 3 × 3 = 2^3 × 3^3 \\ 360 &= 2 × 2 × 2 × 3 × 3 × 5 = 2^3 × 3^2 × 5 Step 2: Wa HCF. HCF = 2^3 × 3^2 = 8 × 9 = 72 Step 3: Wa LCM. LCM = 2^4 × 3^3 × 5^1 = 16 × 27 × 5 = 2160 3. Fun awọn nọmba 280, 105, 175 Step 1: Wa awọn ipin nọmba akọkọ fun nọmba kọọkan. 280 &= 2 × 2 × 2 × 5 × 7 = 2^3 × 5 × 7 \\ 105 &= 3 × 5 × 7 \\ 175 &= 5 × 5 × 7 = 5^2 × 7 Step 2: Wa HCF. HCF = 5^1 × 7^1 = 5 × 7 = 35 Step 3: Wa LCM. LCM = 2^3 × 3^1 × 5^2 × 7^1 = 8 × 3 × 25 × 7 = 4200 4. Fun awọn nọmba 126, 234, 90 Step 1: Wa awọn ipin nọmba akọkọ fun nọmba kọọkan. 126 &= 2 × 3 × 3 × 7 = 2^1 × 3^2 × 7^1 \\ 234 &= 2 × 3 × 3 × 13 = 2^1 × 3^2 × 13^1 \\ 90 &= 2 × 3 × 3 × 5 = 2^1 × 3^2 × 5^1 Step 2: Wa HCF. HCF = 2^1 × 3^2 = 2 × 9 = 18 Step 3: Wa LCM. LCM = 2^1 × 3^2 × 5^1 × 7^1 × 13^1 = 2 × 9 × 5 × 7 × 13 = 8190 5. Fun awọn nọmba 160, 96, 224 Step 1: Wa awọn ipin nọmba akọkọ fun nọmba kọọkan. 160 &= 2 × 2 × 2 × 2 × 2 × 5 = 2^5 × 5^1 \\ 96 &= 2 × 2 × 2 × 2 × 2 × 3 = 2^5 × 3^1 \\ 224 &= 2 × 2 × 2 × 2 × 2 × 7 = 2^5 × 7^1 Step 2: Wa HCF. HCF = 2^5 = 32 Step 3: Wa LCM. LCM = 2^5 × 3^1 × 5^1 × 7^1 = 32 × 3 × 5 × 7 = 3360 Mándame la siguiente 📸
