Steps to Calculate GCD of 745, 809, 421, 506 using LCM Formula
Given numbers are 745, 809, 421, 506
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(745, 809) = 602705
GCD(745, 809) = ( 745 x 809 ) / 602705
= 745 / 809
= 745
Step2:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
Step3:
LCM(1, 506) = 506
GCD(1, 506) = ( 1 x 506 ) / 506
= 1 / 506
= 1
So, Greatest Common Divisor of 745, 809, 421, 506 is 1
