Given numbers are 745, 670, 662, 638

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

Apply this formula for all numbers.

Step1:

LCM(745, 670) = 99830

GCD(745, 670) = ( 745 x 670 ) / 99830

= 745 / 670

= 745

Step2:

LCM(5, 662) = 3310

GCD(5, 662) = ( 5 x 662 ) / 3310

= 5 / 662

= 5

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 745, 670, 662, 638 is 1
