Steps to Calculate GCD of 869, 921, 45, 563 using LCM Formula
Given numbers are 869, 921, 45, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(869, 921) = 800349
GCD(869, 921) = ( 869 x 921 ) / 800349
= 869 / 921
= 869
Step2:
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
= 1 / 45
= 1
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 869, 921, 45, 563 is 1
