GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(676, 906) = 306228
GCD(676, 906) = ( 676 x 906 ) / 306228
= 676 / 906
= 676
Step2:
LCM(2, 878) = 878
GCD(2, 878) = ( 2 x 878 ) / 878
= 2 / 878
= 2
Step3:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
So, Greatest Common Divisor of 676, 906, 878, 620 is 2
