Steps to Calculate GCD of 640, 805, 60, 173 using LCM Formula

Given numbers are 640, 805, 60, 173

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(640, 805) = 103040

GCD(640, 805) = ( 640 x 805 ) / 103040

= 640 / 805

= 640


Step2:

LCM(5, 60) = 60

GCD(5, 60) = ( 5 x 60 ) / 60

= 5 / 60

= 5


Step3:

LCM(5, 173) = 865

GCD(5, 173) = ( 5 x 173 ) / 865

= 5 / 173

= 5


So, Greatest Common Divisor of 640, 805, 60, 173 is 1
