Steps to Calculate GCD of 973, 821, 642, 563 using LCM Formula
Given numbers are 973, 821, 642, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(973, 821) = 798833
GCD(973, 821) = ( 973 x 821 ) / 798833
= 973 / 821
= 973
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 973, 821, 642, 563 is 1
