Given numbers are 915, 428, 335, 647

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

Apply this formula for all numbers.

Step1:

LCM(915, 428) = 391620

GCD(915, 428) = ( 915 x 428 ) / 391620

= 915 / 428

= 915

Step2:

LCM(1, 335) = 335

GCD(1, 335) = ( 1 x 335 ) / 335

= 1 / 335

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 915, 428, 335, 647 is 1
