Steps to Calculate GCD of 135, 698, 649, 257 using LCM Formula
Given numbers are 135, 698, 649, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(135, 698) = 94230
GCD(135, 698) = ( 135 x 698 ) / 94230
= 135 / 698
= 135
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 135, 698, 649, 257 is 1
