Steps to Calculate GCD of 19, 63, 68, 75 using LCM Formula
Given numbers are 19, 63, 68, 75
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(19, 63) = 1197
GCD(19, 63) = ( 19 x 63 ) / 1197
= 19 / 63
= 19
Step2:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
Step3:
LCM(1, 75) = 75
GCD(1, 75) = ( 1 x 75 ) / 75
= 1 / 75
= 1
So, Greatest Common Divisor of 19, 63, 68, 75 is 1
