Given numbers are 329, 643, 781, 148
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(329, 643) = 211547
GCD(329, 643) = ( 329 x 643 ) / 211547
= 329 / 643
= 329
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 329, 643, 781, 148 is 1
