Given numbers are 870, 625, 729, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 625) = 108750
GCD(870, 625) = ( 870 x 625 ) / 108750
= 870 / 625
= 870
Step2:
LCM(5, 729) = 3645
GCD(5, 729) = ( 5 x 729 ) / 3645
= 5 / 729
= 5
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 870, 625, 729, 631 is 1
