Given numbers are 645, 666, 586, 844

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

Apply this formula for all numbers.

Step1:

LCM(645, 666) = 143190

GCD(645, 666) = ( 645 x 666 ) / 143190

= 645 / 666

= 645

Step2:

LCM(3, 586) = 1758

GCD(3, 586) = ( 3 x 586 ) / 1758

= 3 / 586

= 3

Step3:

LCM(1, 844) = 844

GCD(1, 844) = ( 1 x 844 ) / 844

= 1 / 844

= 1

So, Greatest Common Divisor of 645, 666, 586, 844 is 1
