Given numbers are 648, 916, 639, 906

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

Apply this formula for all numbers.

Step1:

LCM(648, 916) = 148392

GCD(648, 916) = ( 648 x 916 ) / 148392

= 648 / 916

= 648

Step2:

LCM(4, 639) = 2556

GCD(4, 639) = ( 4 x 639 ) / 2556

= 4 / 639

= 4

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 648, 916, 639, 906 is 1
