Respuesta :

Answer:

a) 83160

b) 12

Step-by-step explanation:

The prime factors of 840 are 2 x 3 x 5x 7*2*2

Prime factors of 8316 are 2*2*11*3*3*3

a) `Smallest whole number that is divisible by both 840 and 8316

We are supposed to find the LCM of the two numbers which is equal to

2*2*11*5*7*3*3*3*2 = 83160

b) Greatest whole number that will divide both both 840 and 8316
