Given numbers are 308, 660, 648, 987

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

Apply this formula for all numbers.

Step1:

LCM(308, 660) = 4620

GCD(308, 660) = ( 308 x 660 ) / 4620

= 308 / 660

= 308

Step2:

LCM(44, 648) = 7128

GCD(44, 648) = ( 44 x 648 ) / 7128

= 44 / 648

= 44

Step3:

LCM(4, 987) = 3948

GCD(4, 987) = ( 4 x 987 ) / 3948

= 4 / 987

= 4

So, Greatest Common Divisor of 308, 660, 648, 987 is 1
