Given numbers are 464, 142, 81, 678

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

Apply this formula for all numbers.

Step1:

LCM(464, 142) = 32944

GCD(464, 142) = ( 464 x 142 ) / 32944

= 464 / 142

= 464

Step2:

LCM(2, 81) = 162

GCD(2, 81) = ( 2 x 81 ) / 162

= 2 / 81

= 2

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 464, 142, 81, 678 is 1
