Steps to Calculate GCD of 57, 95, 45, 90 using LCM Formula
Given numbers are 57, 95, 45, 90
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(57, 95) = 285
GCD(57, 95) = ( 57 x 95 ) / 285
= 57 / 95
= 57
Step2:
LCM(19, 45) = 855
GCD(19, 45) = ( 19 x 45 ) / 855
= 19 / 45
= 19
Step3:
LCM(1, 90) = 90
GCD(1, 90) = ( 1 x 90 ) / 90
= 1 / 90
= 1
So, Greatest Common Divisor of 57, 95, 45, 90 is 1
