Steps to Calculate GCD of 37, 81, 45, 25 using LCM Formula
Given numbers are 37, 81, 45, 25
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(37, 81) = 2997
GCD(37, 81) = ( 37 x 81 ) / 2997
= 37 / 81
= 37
Step2:
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
= 1 / 45
= 1
Step3:
LCM(1, 25) = 25
GCD(1, 25) = ( 1 x 25 ) / 25
= 1 / 25
= 1
So, Greatest Common Divisor of 37, 81, 45, 25 is 1
