Steps to Calculate GCD of 438, 706, 73, 809 using LCM Formula
Given numbers are 438, 706, 73, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 706) = 154614
GCD(438, 706) = ( 438 x 706 ) / 154614
= 438 / 706
= 438
Step2:
LCM(2, 73) = 146
GCD(2, 73) = ( 2 x 73 ) / 146
= 2 / 73
= 2
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 438, 706, 73, 809 is 1
