To find the greatest possible value of x, we start by prime factorizing the given numbers: 10 = 2 × 5, 14 = 2 × 7, and 70 = 2 × 5 × 7, which is their least common multiple. Since x must also be a multiple of 2, 5, and 7 to have a least common multiple of 70 with 10 and 14, the largest multiple that satisfies these requirements is 70. Therefore, the greatest possible value of x is 70.
### Instruction:
