Find LCM of 942,768,429,980,320 with Prime Factorization
| 2 | 942, 768, 429, 980, 320 |
| 2 | 471, 384, 429, 490, 160 |
| 2 | 471, 192, 429, 245, 80 |
| 2 | 471, 96, 429, 245, 40 |
| 2 | 471, 48, 429, 245, 20 |
| 2 | 471, 24, 429, 245, 10 |
| 3 | 471, 12, 429, 245, 5 |
| 5 | 157, 4, 143, 245, 5 |
| 157, 4, 143, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 157 x 4 x 143 x 49 x 1 = 4224380160
Therefore, the lowest common multiple of 942,768,429,980,320 is 4224380160.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
942 x 768 x 429 x 980 x 320 = 97329718886400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
942 : 1, 2, 3, 6, 157, 314, 471, 942
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
429 : 1, 3, 11, 13, 33, 39, 143, 429
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,768,429,980,320, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
768:2x 2x 2x 2x 2x 2x 2x 2x 3
429:3x 11x 13
980:2x 2x 5x 7x 7
320:2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 2x 2x 2x 3x 3x 5 = 23040
Therefore, the value for common factors is 23040.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 97329718886400/(1x23040)
LCM = 97329718886400/23040
LCM = 4224380160
Thus, we can understand that the LCM of 942,768,429,980,320 is 4224380160.
