Steps to Calculate GCD of 147, 791, 473, 405 using LCM Formula
Given numbers are 147, 791, 473, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 791) = 16611
GCD(147, 791) = ( 147 x 791 ) / 16611
= 147 / 791
= 147
Step2:
LCM(7, 473) = 3311
GCD(7, 473) = ( 7 x 473 ) / 3311
= 7 / 473
= 7
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 147, 791, 473, 405 is 1
