Given numbers are 668, 352, 861, 821

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

Apply this formula for all numbers.

Step1:

LCM(668, 352) = 58784

GCD(668, 352) = ( 668 x 352 ) / 58784

= 668 / 352

= 668

Step2:

LCM(4, 861) = 3444

GCD(4, 861) = ( 4 x 861 ) / 3444

= 4 / 861

= 4

Step3:

LCM(1, 821) = 821

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

= 1 / 821

= 1

So, Greatest Common Divisor of 668, 352, 861, 821 is 1
