Given numbers are 245, 125, 855, 734

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

Apply this formula for all numbers.

Step1:

LCM(245, 125) = 6125

GCD(245, 125) = ( 245 x 125 ) / 6125

= 245 / 125

= 245

Step2:

LCM(5, 855) = 855

GCD(5, 855) = ( 5 x 855 ) / 855

= 5 / 855

= 5

Step3:

LCM(5, 734) = 3670

GCD(5, 734) = ( 5 x 734 ) / 3670

= 5 / 734

= 5

So, Greatest Common Divisor of 245, 125, 855, 734 is 1
