Given numbers are 156, 840, 268, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 840) = 10920
GCD(156, 840) = ( 156 x 840 ) / 10920
= 156 / 840
= 156
Step2:
LCM(12, 268) = 804
GCD(12, 268) = ( 12 x 268 ) / 804
= 12 / 268
= 12
Step3:
LCM(4, 921) = 3684
GCD(4, 921) = ( 4 x 921 ) / 3684
= 4 / 921
= 4
So, Greatest Common Divisor of 156, 840, 268, 921 is 1
