Given numbers are 805, 689, 518, 240
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 689) = 554645
GCD(805, 689) = ( 805 x 689 ) / 554645
= 805 / 689
= 805
Step2:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
Step3:
LCM(1, 240) = 240
GCD(1, 240) = ( 1 x 240 ) / 240
= 1 / 240
= 1
So, Greatest Common Divisor of 805, 689, 518, 240 is 1
