Steps to Calculate GCD of 890, 821, 977, 155 using LCM Formula
Given numbers are 890, 821, 977, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 821) = 730690
GCD(890, 821) = ( 890 x 821 ) / 730690
= 890 / 821
= 890
Step2:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 890, 821, 977, 155 is 1
