Given numbers are 347, 780, 442, 940
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(347, 780) = 270660
GCD(347, 780) = ( 347 x 780 ) / 270660
= 347 / 780
= 347
Step2:
LCM(1, 442) = 442
GCD(1, 442) = ( 1 x 442 ) / 442
= 1 / 442
= 1
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 347, 780, 442, 940 is 1
