Given numbers are 685, 751, 651, 724
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 751) = 514435
GCD(685, 751) = ( 685 x 751 ) / 514435
= 685 / 751
= 685
Step2:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
Step3:
LCM(1, 724) = 724
GCD(1, 724) = ( 1 x 724 ) / 724
= 1 / 724
= 1
So, Greatest Common Divisor of 685, 751, 651, 724 is 1
