Steps to Calculate GCD of 749, 551, 70, 865 using LCM Formula
Given numbers are 749, 551, 70, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 551) = 412699
GCD(749, 551) = ( 749 x 551 ) / 412699
= 749 / 551
= 749
Step2:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 749, 551, 70, 865 is 1
