Given numbers are 388, 778, 870, 451
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(388, 778) = 150932
GCD(388, 778) = ( 388 x 778 ) / 150932
= 388 / 778
= 388
Step2:
LCM(2, 870) = 870
GCD(2, 870) = ( 2 x 870 ) / 870
= 2 / 870
= 2
Step3:
LCM(2, 451) = 902
GCD(2, 451) = ( 2 x 451 ) / 902
= 2 / 451
= 2
So, Greatest Common Divisor of 388, 778, 870, 451 is 1
