GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 140) = 5460
GCD(780, 140) = ( 780 x 140 ) / 5460
= 780 / 140
= 780
Step2:
LCM(20, 502) = 5020
GCD(20, 502) = ( 20 x 502 ) / 5020
= 20 / 502
= 20
Step3:
LCM(2, 972) = 972
GCD(2, 972) = ( 2 x 972 ) / 972
= 2 / 972
= 2
So, Greatest Common Divisor of 780, 140, 502, 972 is 2
