Given numbers are 900, 861, 108, 987
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(900, 861) = 258300
GCD(900, 861) = ( 900 x 861 ) / 258300
= 900 / 861
= 900
Step2:
LCM(3, 108) = 108
GCD(3, 108) = ( 3 x 108 ) / 108
= 3 / 108
= 3
Step3:
LCM(3, 987) = 987
GCD(3, 987) = ( 3 x 987 ) / 987
= 3 / 987
= 3
So, Greatest Common Divisor of 900, 861, 108, 987 is 3
