Find LCM of 920,210,698,427,345 with Prime Factorization
| 2 | 920, 210, 698, 427, 345 |
| 3 | 460, 105, 349, 427, 345 |
| 5 | 460, 35, 349, 427, 115 |
| 7 | 92, 7, 349, 427, 23 |
| 23 | 92, 1, 349, 61, 23 |
| 4, 1, 349, 61, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 4 x 1 x 349 x 61 x 1 = 411303480
Therefore, the lowest common multiple of 920,210,698,427,345 is 411303480.
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.
920 x 210 x 698 x 427 x 345 = 19865958084000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
698 : 1, 2, 349, 698
427 : 1, 7, 61, 427
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,210,698,427,345, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
210:2x 3x 5x 7
698:2x 349
427:7x 61
345:3x 5x 23
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 3x 5x 5x 7x 23 = 48300
Therefore, the value for common factors is 48300.
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 = 19865958084000/(1x48300)
LCM = 19865958084000/48300
LCM = 411303480
Thus, we can understand that the LCM of 920,210,698,427,345 is 411303480.
