Steps to Calculate GCD of 253, 655, 17, 402 using LCM Formula
Given numbers are 253, 655, 17, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 655) = 165715
GCD(253, 655) = ( 253 x 655 ) / 165715
= 253 / 655
= 253
Step2:
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
= 1 / 17
= 1
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 253, 655, 17, 402 is 1
