Steps to Calculate GCD of 246, 771, 355, 398 using LCM Formula
Given numbers are 246, 771, 355, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(246, 771) = 63222
GCD(246, 771) = ( 246 x 771 ) / 63222
= 246 / 771
= 246
Step2:
LCM(3, 355) = 1065
GCD(3, 355) = ( 3 x 355 ) / 1065
= 3 / 355
= 3
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 246, 771, 355, 398 is 1
