Given numbers are 981, 945, 422, 219

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

Apply this formula for all numbers.

Step1:

LCM(981, 945) = 103005

GCD(981, 945) = ( 981 x 945 ) / 103005

= 981 / 945

= 981

Step2:

LCM(9, 422) = 3798

GCD(9, 422) = ( 9 x 422 ) / 3798

= 9 / 422

= 9

Step3:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

So, Greatest Common Divisor of 981, 945, 422, 219 is 1
