Steps to Calculate GCD of 64, 19, 17, 15 using LCM Formula
Given numbers are 64, 19, 17, 15
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(64, 19) = 1216
GCD(64, 19) = ( 64 x 19 ) / 1216
= 64 / 19
= 64
Step2:
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
= 1 / 17
= 1
Step3:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
So, Greatest Common Divisor of 64, 19, 17, 15 is 1
