Prime factors of 21 are: 3 and 7 Prime factors of 40 are: 23 and 5 LCM = 23*3*5*7 = 840
2 x 420 3 x 280 4 x 210 5 x 168 6 x 140
Well, isn't that a happy little question! Let's take a look at 840. Its factors are numbers that can be multiplied together to give 840, like 1, 2, 3, 4, and so on. The prime factors are the factors that are also prime numbers, like 2, 3, 5, and 7. Just like painting a beautiful landscape, understanding factors can help us see the beauty in numbers!
Yes, since 350 and 840 are NOT relatively prime. 350/840 will be reduced to 5/12.
840- 2 2 2 5 7 3840- 2 3rd power, *5*7*3840- 2*2*2*5*7*3
2x2x2x3x5x7.
840 = 23 x 31 x 51 x 71
They are: 3*5*7*8 = 840, except they are factors.
