Given numbers are 812, 655, 659, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 655) = 531860
GCD(812, 655) = ( 812 x 655 ) / 531860
= 812 / 655
= 812
Step2:
LCM(1, 659) = 659
GCD(1, 659) = ( 1 x 659 ) / 659
= 1 / 659
= 1
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 812, 655, 659, 721 is 1
