Given numbers are 306, 387, 143, 956
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(306, 387) = 13158
GCD(306, 387) = ( 306 x 387 ) / 13158
= 306 / 387
= 306
Step2:
LCM(9, 143) = 1287
GCD(9, 143) = ( 9 x 143 ) / 1287
= 9 / 143
= 9
Step3:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
So, Greatest Common Divisor of 306, 387, 143, 956 is 1
