The Highest Common Factor (HCF) of 280 and 180 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm or prime factorization method. In this case, the prime factorization of 280 is 2^3 * 5 * 7 and the prime factorization of 180 is 2^2 * 3^2 * 5. The common factors between the two numbers are 2^2 and 5, so the HCF of 280 and 180 is 20.
2*2*2*5*72 x 2 x 2 x 5 x 7 = 280
As a product of its prime factors: 2*2*2*5*7 = 280
yes it is relatively prime
280 = 23 x 5 x 7

It is: 2, 2, 2, 5 and 7
2 x 2 x 2 x 5 x 7 = 280
280 = 2 x 2 x 2 x 5 x 7
2*2*2*5*72 x 2 x 2 x 5 x 7 = 280
2 x 2 x 2 x 5 x 7 = 280, the LCM
The prime factorization of 280 is: 2 x 140 2 x 2 x 70 2 x 2 x 2 x 35 2 x 2 x 2 x 5 x 7. The three prime factors of 280 are 2, 5, 7.
2 x 2 x 2 x 3 x 3 x 3 x 5 x 5 x 5 = 27,000
To find the LCM, first, find the prime factorization of each number:280 = 2 * 2 * 2 * 5 * 7392 = 2 * 2 * 2 * 7 * 7Group the like prime factors (the ones in bold italics)2 * 2 * 2 * 5 * 7 * 7 = 1960
