o 10 ⁵

Answer 1

The product of all the prime numbers less than 20 is closest to 10^7.

Step-by-step explanation:

The product of all the prime numbers less than 20 can be found by multiplying the prime numbers together: 2 x 3 x 5 x 7 x 11 x 13 x 17 x 19. Let's calculate this product.

2 x 3 = 6

6 x 5 = 30

30 x 7 = 210

210 x 11 = 2310

2310 x 13 = 30030

30030 x 17 = 510510

510510 x 19 = 9699690

The product of all the prime numbers less than 20 is closest to 107.
