GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 684) = 8892
GCD(156, 684) = ( 156 x 684 ) / 8892
= 156 / 684
= 156
Step2:
LCM(12, 909) = 3636
GCD(12, 909) = ( 12 x 909 ) / 3636
= 12 / 909
= 12
Step3:
LCM(3, 380) = 1140
GCD(3, 380) = ( 3 x 380 ) / 1140
= 3 / 380
= 3
So, Greatest Common Divisor of 156, 684, 909, 380 is 1
