Given numbers are 791, 904, 780, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 904) = 6328
GCD(791, 904) = ( 791 x 904 ) / 6328
= 791 / 904
= 791
Step2:
LCM(113, 780) = 88140
GCD(113, 780) = ( 113 x 780 ) / 88140
= 113 / 780
= 113
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 791, 904, 780, 628 is 1
