Given numbers are 247, 975, 445, 196

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

Apply this formula for all numbers.

Step1:

LCM(247, 975) = 18525

GCD(247, 975) = ( 247 x 975 ) / 18525

= 247 / 975

= 247

Step2:

LCM(13, 445) = 5785

GCD(13, 445) = ( 13 x 445 ) / 5785

= 13 / 445

= 13

Step3:

LCM(1, 196) = 196

GCD(1, 196) = ( 1 x 196 ) / 196

= 1 / 196

= 1

So, Greatest Common Divisor of 247, 975, 445, 196 is 1
