Given numbers are 358, 185, 172, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(358, 185) = 66230
GCD(358, 185) = ( 358 x 185 ) / 66230
= 358 / 185
= 358
Step2:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 358, 185, 172, 287 is 1
