Given numbers are 370, 645, 647, 223

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

Apply this formula for all numbers.

Step1:

LCM(370, 645) = 47730

GCD(370, 645) = ( 370 x 645 ) / 47730

= 370 / 645

= 370

Step2:

LCM(5, 647) = 3235

GCD(5, 647) = ( 5 x 647 ) / 3235

= 5 / 647

= 5

Step3:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

So, Greatest Common Divisor of 370, 645, 647, 223 is 1
