Steps to Calculate GCD of 105, 147, 551, 156 using LCM Formula
Given numbers are 105, 147, 551, 156
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 147) = 735
GCD(105, 147) = ( 105 x 147 ) / 735
= 105 / 147
= 105
Step2:
LCM(21, 551) = 11571
GCD(21, 551) = ( 21 x 551 ) / 11571
= 21 / 551
= 21
Step3:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
So, Greatest Common Divisor of 105, 147, 551, 156 is 1
