Steps to Calculate GCD of 563, 257, 653, 505 using LCM Formula
Given numbers are 563, 257, 653, 505
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(563, 257) = 144691
GCD(563, 257) = ( 563 x 257 ) / 144691
= 563 / 257
= 563
Step2:
LCM(1, 653) = 653
GCD(1, 653) = ( 1 x 653 ) / 653
= 1 / 653
= 1
Step3:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
So, Greatest Common Divisor of 563, 257, 653, 505 is 1
