Given numbers are 638, 153, 832, 838

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

Apply this formula for all numbers.

Step1:

LCM(638, 153) = 97614

GCD(638, 153) = ( 638 x 153 ) / 97614

= 638 / 153

= 638

Step2:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 638, 153, 832, 838 is 1
