Given numbers are 157, 870, 280, 430

The list of prime factors of all numbers are

Prime factors of 157 are 157

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 430 are 2 x 5 x 43

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 157, 870, 280, 430

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(157, 870) = 136590

GCD(157, 870) = ( 157 x 870 ) / 136590

= 157 / 870

= 157

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 157, 870, 280, 430 is 1
