Given numbers are 915, 135, 633, 661

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

Apply this formula for all numbers.

Step1:

LCM(915, 135) = 8235

GCD(915, 135) = ( 915 x 135 ) / 8235

= 915 / 135

= 915

Step2:

LCM(15, 633) = 3165

GCD(15, 633) = ( 15 x 633 ) / 3165

= 15 / 633

= 15

Step3:

LCM(3, 661) = 1983

GCD(3, 661) = ( 3 x 661 ) / 1983

= 3 / 661

= 3

So, Greatest Common Divisor of 915, 135, 633, 661 is 1
