Given numbers are 987, 617, 225, 543
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 617) = 608979
GCD(987, 617) = ( 987 x 617 ) / 608979
= 987 / 617
= 987
Step2:
LCM(1, 225) = 225
GCD(1, 225) = ( 1 x 225 ) / 225
= 1 / 225
= 1
Step3:
LCM(1, 543) = 543
GCD(1, 543) = ( 1 x 543 ) / 543
= 1 / 543
= 1
So, Greatest Common Divisor of 987, 617, 225, 543 is 1
