Steps to Calculate GCD of 985, 519, 605, 257 using LCM Formula
Given numbers are 985, 519, 605, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 519) = 511215
GCD(985, 519) = ( 985 x 519 ) / 511215
= 985 / 519
= 985
Step2:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 985, 519, 605, 257 is 1
