The multiples of 20 are numbers that can be divided evenly by 20. To find the multiples of 20 up to 1000, you can start by listing the multiples in increments of 20: 20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500, 520, 540, 560, 580, 600, 620, 640, 660, 680, 700, 720, 740, 760, 780, 800, 820, 840, 860, 880, 900, 920, 940, 960, 980, 1000.
Oh, isn't that just lovely? Let's paint a picture with multiples of 7 up to 700. So, we start with 7, then add 7 each time: 7, 14, 21, 28, and so on, all the way up to 700. Just imagine each multiple of 7 as a happy little tree in our mathematical landscape.
at least 700 or higher

No. A factor is a number or algebraic expression by which another is exactly divisible. A multiple is a number that can be divided by another number without a remainder. Factors go into numbers, numbers go into multiples.
