Steps to Calculate GCD of 685, 239, 742, 751 using LCM Formula
Given numbers are 685, 239, 742, 751
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 239) = 163715
GCD(685, 239) = ( 685 x 239 ) / 163715
= 685 / 239
= 685
Step2:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
Step3:
LCM(1, 751) = 751
GCD(1, 751) = ( 1 x 751 ) / 751
= 1 / 751
= 1
So, Greatest Common Divisor of 685, 239, 742, 751 is 1
