Given numbers are 156, 745, 906, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 745) = 116220
GCD(156, 745) = ( 156 x 745 ) / 116220
= 156 / 745
= 156
Step2:
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
= 1 / 906
= 1
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 156, 745, 906, 620 is 1
