Steps to Calculate GCD of 428, 368, 17, 813 using LCM Formula
Given numbers are 428, 368, 17, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 368) = 39376
GCD(428, 368) = ( 428 x 368 ) / 39376
= 428 / 368
= 428
Step2:
LCM(4, 17) = 68
GCD(4, 17) = ( 4 x 17 ) / 68
= 4 / 17
= 4
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 428, 368, 17, 813 is 1
