Given numbers are 340, 663, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 663) = 13260
GCD(340, 663) = ( 340 x 663 ) / 13260
= 340 / 663
= 340
Step2:
LCM(17, 257) = 4369
GCD(17, 257) = ( 17 x 257 ) / 4369
= 17 / 257
= 17
So, Greatest Common Divisor of 340, 663, 257 is 1
