Steps to Calculate GCD of 403, 781, 278, 499 using LCM Formula
Given numbers are 403, 781, 278, 499
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 781) = 314743
GCD(403, 781) = ( 403 x 781 ) / 314743
= 403 / 781
= 403
Step2:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
Step3:
LCM(1, 499) = 499
GCD(1, 499) = ( 1 x 499 ) / 499
= 1 / 499
= 1
So, Greatest Common Divisor of 403, 781, 278, 499 is 1
