GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 637) = 71981
GCD(791, 637) = ( 791 x 637 ) / 71981
= 791 / 637
= 791
Step2:
LCM(7, 785) = 5495
GCD(7, 785) = ( 7 x 785 ) / 5495
= 7 / 785
= 7
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 791, 637, 785, 563 is 1
