Given numbers are 670, 988, 668, 143

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

Apply this formula for all numbers.

Step1:

LCM(670, 988) = 330980

GCD(670, 988) = ( 670 x 988 ) / 330980

= 670 / 988

= 670

Step2:

LCM(2, 668) = 668

GCD(2, 668) = ( 2 x 668 ) / 668

= 2 / 668

= 2

Step3:

LCM(2, 143) = 286

GCD(2, 143) = ( 2 x 143 ) / 286

= 2 / 143

= 2

So, Greatest Common Divisor of 670, 988, 668, 143 is 1
