Given numbers are 745, 890, 258, 109

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

Apply this formula for all numbers.

Step1:

LCM(745, 890) = 132610

GCD(745, 890) = ( 745 x 890 ) / 132610

= 745 / 890

= 745

Step2:

LCM(5, 258) = 1290

GCD(5, 258) = ( 5 x 258 ) / 1290

= 5 / 258

= 5

Step3:

LCM(1, 109) = 109

GCD(1, 109) = ( 1 x 109 ) / 109

= 1 / 109

= 1

So, Greatest Common Divisor of 745, 890, 258, 109 is 1
