Steps to Calculate GCD of 671, 675, 155, 457 using LCM Formula
Given numbers are 671, 675, 155, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 675) = 452925
GCD(671, 675) = ( 671 x 675 ) / 452925
= 671 / 675
= 671
Step2:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 671, 675, 155, 457 is 1
