GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(109, 961) = 104749
GCD(109, 961) = ( 109 x 961 ) / 104749
= 109 / 961
= 109
Step2:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 109, 961, 187, 257 is 1
