Steps to Calculate GCD of 397, 443, 287, 771 using LCM Formula
Given numbers are 397, 443, 287, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 443) = 175871
GCD(397, 443) = ( 397 x 443 ) / 175871
= 397 / 443
= 397
Step2:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 397, 443, 287, 771 is 1
