Given numbers are 747, 945, 406, 218

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(747, 945) = 78435

GCD(747, 945) = ( 747 x 945 ) / 78435

= 747 / 945

= 747

Step2:

LCM(9, 406) = 3654

GCD(9, 406) = ( 9 x 406 ) / 3654

= 9 / 406

= 9

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 747, 945, 406, 218 is 1
