Given numbers are 240, 278, 328, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 278) = 33360
GCD(240, 278) = ( 240 x 278 ) / 33360
= 240 / 278
= 240
Step2:
LCM(2, 328) = 328
GCD(2, 328) = ( 2 x 328 ) / 328
= 2 / 328
= 2
Step3:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
So, Greatest Common Divisor of 240, 278, 328, 805 is 1
