Given numbers are 665, 487, 140, 946

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

Apply this formula for all numbers.

Step1:

LCM(665, 487) = 323855

GCD(665, 487) = ( 665 x 487 ) / 323855

= 665 / 487

= 665

Step2:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

Step3:

LCM(1, 946) = 946

GCD(1, 946) = ( 1 x 946 ) / 946

= 1 / 946

= 1

So, Greatest Common Divisor of 665, 487, 140, 946 is 1
