Given numbers are 665, 217, 571, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 217) = 20615
GCD(665, 217) = ( 665 x 217 ) / 20615
= 665 / 217
= 665
Step2:
LCM(7, 571) = 3997
GCD(7, 571) = ( 7 x 571 ) / 3997
= 7 / 571
= 7
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 665, 217, 571, 668 is 1
