Steps to Calculate GCD of 658, 686, 879, 551 using LCM Formula
Given numbers are 658, 686, 879, 551
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 686) = 32242
GCD(658, 686) = ( 658 x 686 ) / 32242
= 658 / 686
= 658
Step2:
LCM(14, 879) = 12306
GCD(14, 879) = ( 14 x 879 ) / 12306
= 14 / 879
= 14
Step3:
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
= 1 / 551
= 1
So, Greatest Common Divisor of 658, 686, 879, 551 is 1
