GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 948) = 258804
GCD(819, 948) = ( 819 x 948 ) / 258804
= 819 / 948
= 819
Step2:
LCM(3, 781) = 2343
GCD(3, 781) = ( 3 x 781 ) / 2343
= 3 / 781
= 3
Step3:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 819, 948, 781, 126 is 1
