Given numbers are 581, 816, 187, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(581, 816) = 474096
GCD(581, 816) = ( 581 x 816 ) / 474096
= 581 / 816
= 581
Step2:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 581, 816, 187, 647 is 1
