GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 477) = 24804
GCD(156, 477) = ( 156 x 477 ) / 24804
= 156 / 477
= 156
Step2:
LCM(3, 747) = 747
GCD(3, 747) = ( 3 x 747 ) / 747
= 3 / 747
= 3
Step3:
LCM(3, 190) = 570
GCD(3, 190) = ( 3 x 190 ) / 570
= 3 / 190
= 3
So, Greatest Common Divisor of 156, 477, 747, 190 is 1
