Given numbers are 448, 270, 247, 109
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(448, 270) = 60480
GCD(448, 270) = ( 448 x 270 ) / 60480
= 448 / 270
= 448
Step2:
LCM(2, 247) = 494
GCD(2, 247) = ( 2 x 247 ) / 494
= 2 / 247
= 2
Step3:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
So, Greatest Common Divisor of 448, 270, 247, 109 is 1
