Steps to Calculate GCD of 853, 783, 663, 257 using LCM Formula
Given numbers are 853, 783, 663, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(853, 783) = 667899
GCD(853, 783) = ( 853 x 783 ) / 667899
= 853 / 783
= 853
Step2:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 853, 783, 663, 257 is 1
