GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 791) = 544208
GCD(688, 791) = ( 688 x 791 ) / 544208
= 688 / 791
= 688
Step2:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
Step3:
LCM(1, 739) = 739
GCD(1, 739) = ( 1 x 739 ) / 739
= 1 / 739
= 1
So, Greatest Common Divisor of 688, 791, 280, 739 is 1
