Given numbers are 915, 840, 699, 920

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 699 are 3 x 233

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 915, 840, 699, 920

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

Apply this formula for all numbers.

Step1:

LCM(915, 840) = 51240

GCD(915, 840) = ( 915 x 840 ) / 51240

= 915 / 840

= 915

Step2:

LCM(15, 699) = 3495

GCD(15, 699) = ( 15 x 699 ) / 3495

= 15 / 699

= 15

Step3:

LCM(3, 920) = 2760

GCD(3, 920) = ( 3 x 920 ) / 2760

= 3 / 920

= 3

So, Greatest Common Divisor of 915, 840, 699, 920 is 1
