Given numbers are 915, 147, 639, 523

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

Apply this formula for all numbers.

Step1:

LCM(915, 147) = 44835

GCD(915, 147) = ( 915 x 147 ) / 44835

= 915 / 147

= 915

Step2:

LCM(3, 639) = 639

GCD(3, 639) = ( 3 x 639 ) / 639

= 3 / 639

= 3

Step3:

LCM(3, 523) = 1569

GCD(3, 523) = ( 3 x 523 ) / 1569

= 3 / 523

= 3

So, Greatest Common Divisor of 915, 147, 639, 523 is 1
