Steps to Calculate GCD of 479, 782, 115, 405 using LCM Formula
Given numbers are 479, 782, 115, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(479, 782) = 374578
GCD(479, 782) = ( 479 x 782 ) / 374578
= 479 / 782
= 479
Step2:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 479, 782, 115, 405 is 1
