What is the LCM and the HCF of 18 and 70?
18 = 2 * 3 * 370 = 2 * 5 * 7Thus:LCM = 2*3*3*5*7 = 630HCF = 2
How do you find HCF of product of 2 nos?
You find the HCF of the two numbers, not their product. Example: 30 and 42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the HCF
What is the HCF of 16x27x49 and 8x27x125?
hcf(16×27×49, 8×2725) = 8×27 = 216 Using prime factorisation: 16×27×49 = 2⁴ × 3³ × 7² 8×27×125 = 2³ × 3³ × 5³ → hcf = 2³ × 3³ = 8×27 = 216
HCF by prime factorization by short division method?
1. HCF by factorisation Method: HCF is the product of common factors of all the numbers. Example: HCF of 24, 48, 60 First find the prime factors of these numbers 2 |24 2|48 2|60 24= 2*2*2*3 2|12 2|24 2|30 48= 2*2*2*2*3 2|6 2|12 3|15 60= 2*2*3*5 3|3 2|6 5|5 HCF= 2*2*3=12 |1 3|3 |1 |1 2. Division Method: Divide the larger number by the smaller number. Now divide the devisor by the remainder. Continue the process till the remainder is zero. Now this last devisor is the HCF of those two numbers. Repeat the process between this HCF and the other number. 48)60(1 48 12)48(4 48 0 12)60(5 60 0 Ans: 12
What is the HCF of 48 and 224?
16 48 = 2^4 x 3 224 = 2^5 x 7 hcf = 2^4 = 16

What is the hcf and LCM of 14 and 30?
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
What is the HCF and LCM of 270 and 195?
hcf = 15 lcm = 3510 270 = 2 x 33 x 5 195 = 3 x 5 x 13 hcf = 3 x 5 = 15 lcm = 2 x 33 x 5 x 13 = 3510
What is the LCM and the HCF of 18 and 70?
18 = 2 * 3 * 370 = 2 * 5 * 7Thus:LCM = 2*3*3*5*7 = 630HCF = 2
