Given numbers are 868, 924, 409, 648

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

Apply this formula for all numbers.

Step1:

LCM(868, 924) = 28644

GCD(868, 924) = ( 868 x 924 ) / 28644

= 868 / 924

= 868

Step2:

LCM(28, 409) = 11452

GCD(28, 409) = ( 28 x 409 ) / 11452

= 28 / 409

= 28

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 868, 924, 409, 648 is 1
