Given numbers are 671, 143, 427, 972

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

Apply this formula for all numbers.

Step1:

LCM(671, 143) = 8723

GCD(671, 143) = ( 671 x 143 ) / 8723

= 671 / 143

= 671

Step2:

LCM(11, 427) = 4697

GCD(11, 427) = ( 11 x 427 ) / 4697

= 11 / 427

= 11

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 671, 143, 427, 972 is 1
