Steps to Calculate GCD of 680, 740, 720, 239 using LCM Formula

Given numbers are 680, 740, 720, 239

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

Apply this formula for all numbers.

Step1:

LCM(680, 740) = 25160

GCD(680, 740) = ( 680 x 740 ) / 25160

= 680 / 740

= 680


Step2:

LCM(20, 720) = 720

GCD(20, 720) = ( 20 x 720 ) / 720

= 20 / 720

= 20


Step3:

LCM(20, 239) = 4780

GCD(20, 239) = ( 20 x 239 ) / 4780

= 20 / 239

= 20


So, Greatest Common Divisor of 680, 740, 720, 239 is 1
