Given numbers are 812, 618, 879, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 618) = 250908
GCD(812, 618) = ( 812 x 618 ) / 250908
= 812 / 618
= 812
Step2:
LCM(2, 879) = 1758
GCD(2, 879) = ( 2 x 879 ) / 1758
= 2 / 879
= 2
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 812, 618, 879, 865 is 1
