Steps to Calculate GCD of 438, 147, 530, 253 using LCM Formula
Given numbers are 438, 147, 530, 253
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 147) = 21462
GCD(438, 147) = ( 438 x 147 ) / 21462
= 438 / 147
= 438
Step2:
LCM(3, 530) = 1590
GCD(3, 530) = ( 3 x 530 ) / 1590
= 3 / 530
= 3
Step3:
LCM(1, 253) = 253
GCD(1, 253) = ( 1 x 253 ) / 253
= 1 / 253
= 1
So, Greatest Common Divisor of 438, 147, 530, 253 is 1
