Given numbers are 653, 981, 821, 868

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

Apply this formula for all numbers.

Step1:

LCM(653, 981) = 640593

GCD(653, 981) = ( 653 x 981 ) / 640593

= 653 / 981

= 653

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

So, Greatest Common Divisor of 653, 981, 821, 868 is 1
