GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 794) = 572474
GCD(721, 794) = ( 721 x 794 ) / 572474
= 721 / 794
= 721
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
So, Greatest Common Divisor of 721, 794, 530, 486 is 1
