Given numbers are 783, 120, 707, 634
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(783, 120) = 31320
GCD(783, 120) = ( 783 x 120 ) / 31320
= 783 / 120
= 783
Step2:
LCM(3, 707) = 2121
GCD(3, 707) = ( 3 x 707 ) / 2121
= 3 / 707
= 3
Step3:
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
= 1 / 634
= 1
So, Greatest Common Divisor of 783, 120, 707, 634 is 1
