Given numbers are 393, 302, 476, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 302) = 118686
GCD(393, 302) = ( 393 x 302 ) / 118686
= 393 / 302
= 393
Step2:
LCM(1, 476) = 476
GCD(1, 476) = ( 1 x 476 ) / 476
= 1 / 476
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 393, 302, 476, 781 is 1
