Steps to Calculate GCD of 553, 455, 64, 158 using LCM Formula
Given numbers are 553, 455, 64, 158
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(553, 455) = 35945
GCD(553, 455) = ( 553 x 455 ) / 35945
= 553 / 455
= 553
Step2:
LCM(7, 64) = 448
GCD(7, 64) = ( 7 x 64 ) / 448
= 7 / 64
= 7
Step3:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
So, Greatest Common Divisor of 553, 455, 64, 158 is 1
