Given numbers are 157, 240, 245, 920

The list of prime factors of all numbers are

Prime factors of 157 are 157

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 245 are 5 x 7 x 7

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 157, 240, 245, 920

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

Apply this formula for all numbers.

Step1:

LCM(157, 240) = 37680

GCD(157, 240) = ( 157 x 240 ) / 37680

= 157 / 240

= 157

Step2:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 157, 240, 245, 920 is 1
