Given numbers are 655, 355, 240, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 355) = 46505
GCD(655, 355) = ( 655 x 355 ) / 46505
= 655 / 355
= 655
Step2:
LCM(5, 240) = 240
GCD(5, 240) = ( 5 x 240 ) / 240
= 5 / 240
= 5
Step3:
LCM(5, 680) = 680
GCD(5, 680) = ( 5 x 680 ) / 680
= 5 / 680
= 5
So, Greatest Common Divisor of 655, 355, 240, 680 is 5
