Given numbers are 987, 551, 483, 403
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 551) = 543837
GCD(987, 551) = ( 987 x 551 ) / 543837
= 987 / 551
= 987
Step2:
LCM(1, 483) = 483
GCD(1, 483) = ( 1 x 483 ) / 483
= 1 / 483
= 1
Step3:
LCM(1, 403) = 403
GCD(1, 403) = ( 1 x 403 ) / 403
= 1 / 403
= 1
So, Greatest Common Divisor of 987, 551, 483, 403 is 1
