Given numbers are 747, 491, 156

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

Apply this formula for all numbers.

Step1:

LCM(747, 491) = 366777

GCD(747, 491) = ( 747 x 491 ) / 366777

= 747 / 491

= 747

Step2:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 747, 491, 156 is 1
