Given numbers are 390, 147, 652, 948
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 147) = 19110
GCD(390, 147) = ( 390 x 147 ) / 19110
= 390 / 147
= 390
Step2:
LCM(3, 652) = 1956
GCD(3, 652) = ( 3 x 652 ) / 1956
= 3 / 652
= 3
Step3:
LCM(1, 948) = 948
GCD(1, 948) = ( 1 x 948 ) / 948
= 1 / 948
= 1
So, Greatest Common Divisor of 390, 147, 652, 948 is 1
