Given numbers are 915, 861, 607, 691

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

Apply this formula for all numbers.

Step1:

LCM(915, 861) = 262605

GCD(915, 861) = ( 915 x 861 ) / 262605

= 915 / 861

= 915

Step2:

LCM(3, 607) = 1821

GCD(3, 607) = ( 3 x 607 ) / 1821

= 3 / 607

= 3

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 915, 861, 607, 691 is 1
