Steps to Calculate GCD of 15, 58, 34, 40 using LCM Formula
Given numbers are 15, 58, 34, 40
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(15, 58) = 870
GCD(15, 58) = ( 15 x 58 ) / 870
= 15 / 58
= 15
Step2:
LCM(1, 34) = 34
GCD(1, 34) = ( 1 x 34 ) / 34
= 1 / 34
= 1
Step3:
LCM(1, 40) = 40
GCD(1, 40) = ( 1 x 40 ) / 40
= 1 / 40
= 1
So, Greatest Common Divisor of 15, 58, 34, 40 is 1
