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

Given numbers are 656, 306, 915, 919

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

Apply this formula for all numbers.

Step1:

LCM(656, 306) = 100368

GCD(656, 306) = ( 656 x 306 ) / 100368

= 656 / 306

= 656

Step2:

LCM(2, 915) = 1830

GCD(2, 915) = ( 2 x 915 ) / 1830

= 2 / 915

= 2

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 656, 306, 915, 919 is 1
