GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 138) = 6762
GCD(147, 138) = ( 147 x 138 ) / 6762
= 147 / 138
= 147
Step2:
LCM(3, 276) = 276
GCD(3, 276) = ( 3 x 276 ) / 276
= 3 / 276
= 3
Step3:
LCM(3, 945) = 945
GCD(3, 945) = ( 3 x 945 ) / 945
= 3 / 945
= 3
So, Greatest Common Divisor of 147, 138, 276, 945 is 3
