Given numbers are 554, 448, 637, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(554, 448) = 124096
GCD(554, 448) = ( 554 x 448 ) / 124096
= 554 / 448
= 554
Step2:
LCM(2, 637) = 1274
GCD(2, 637) = ( 2 x 637 ) / 1274
= 2 / 637
= 2
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 554, 448, 637, 247 is 1
