Given numbers are 287, 651, 395, 194
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 651) = 26691
GCD(287, 651) = ( 287 x 651 ) / 26691
= 287 / 651
= 287
Step2:
LCM(7, 395) = 2765
GCD(7, 395) = ( 7 x 395 ) / 2765
= 7 / 395
= 7
Step3:
LCM(1, 194) = 194
GCD(1, 194) = ( 1 x 194 ) / 194
= 1 / 194
= 1
So, Greatest Common Divisor of 287, 651, 395, 194 is 1
