Given numbers are 105, 665, 614, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 665) = 1995
GCD(105, 665) = ( 105 x 665 ) / 1995
= 105 / 665
= 105
Step2:
LCM(35, 614) = 21490
GCD(35, 614) = ( 35 x 614 ) / 21490
= 35 / 614
= 35
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 105, 665, 614, 257 is 1
