Given numbers are 665, 605, 729, 142

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

Apply this formula for all numbers.

Step1:

LCM(665, 605) = 80465

GCD(665, 605) = ( 665 x 605 ) / 80465

= 665 / 605

= 665

Step2:

LCM(5, 729) = 3645

GCD(5, 729) = ( 5 x 729 ) / 3645

= 5 / 729

= 5

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 665, 605, 729, 142 is 1
