Given numbers are 448, 988, 215, 247

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

Apply this formula for all numbers.

Step1:

LCM(448, 988) = 110656

GCD(448, 988) = ( 448 x 988 ) / 110656

= 448 / 988

= 448

Step2:

LCM(4, 215) = 860

GCD(4, 215) = ( 4 x 215 ) / 860

= 4 / 215

= 4

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 448, 988, 215, 247 is 1
