Given numbers are 668, 240, 125, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 240) = 40080
GCD(668, 240) = ( 668 x 240 ) / 40080
= 668 / 240
= 668
Step2:
LCM(4, 125) = 500
GCD(4, 125) = ( 4 x 125 ) / 500
= 4 / 125
= 4
Step3:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
So, Greatest Common Divisor of 668, 240, 125, 731 is 1
