Given numbers are 448, 457, 380, 516
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(448, 457) = 204736
GCD(448, 457) = ( 448 x 457 ) / 204736
= 448 / 457
= 448
Step2:
LCM(1, 380) = 380
GCD(1, 380) = ( 1 x 380 ) / 380
= 1 / 380
= 1
Step3:
LCM(1, 516) = 516
GCD(1, 516) = ( 1 x 516 ) / 516
= 1 / 516
= 1
So, Greatest Common Divisor of 448, 457, 380, 516 is 1
