GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 872) = 651384
GCD(747, 872) = ( 747 x 872 ) / 651384
= 747 / 872
= 747
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
So, Greatest Common Divisor of 747, 872, 780, 662 is 1
