GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(448, 428) = 47936
GCD(448, 428) = ( 448 x 428 ) / 47936
= 448 / 428
= 448
Step2:
LCM(4, 818) = 1636
GCD(4, 818) = ( 4 x 818 ) / 1636
= 4 / 818
= 4
Step3:
LCM(2, 380) = 380
GCD(2, 380) = ( 2 x 380 ) / 380
= 2 / 380
= 2
So, Greatest Common Divisor of 448, 428, 818, 380 is 2
