Given numbers are 987, 405, 66, 906
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 405) = 133245
GCD(987, 405) = ( 987 x 405 ) / 133245
= 987 / 405
= 987
Step2:
LCM(3, 66) = 66
GCD(3, 66) = ( 3 x 66 ) / 66
= 3 / 66
= 3
Step3:
LCM(3, 906) = 906
GCD(3, 906) = ( 3 x 906 ) / 906
= 3 / 906
= 3
So, Greatest Common Divisor of 987, 405, 66, 906 is 3
