Given numbers are 981, 447, 13, 143

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

Apply this formula for all numbers.

Step1:

LCM(981, 447) = 146169

GCD(981, 447) = ( 981 x 447 ) / 146169

= 981 / 447

= 981

Step2:

LCM(3, 13) = 39

GCD(3, 13) = ( 3 x 13 ) / 39

= 3 / 13

= 3

Step3:

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

= 1 / 143

= 1

So, Greatest Common Divisor of 981, 447, 13, 143 is 1
