Find LCM of 670,225,745,492,943 with Prime Factorization
| 2 | 670, 225, 745, 492, 943 |
| 3 | 335, 225, 745, 246, 943 |
| 5 | 335, 75, 745, 82, 943 |
| 41 | 67, 15, 149, 82, 943 |
| 67, 15, 149, 2, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 67 x 15 x 149 x 2 x 23 = 8472572100
Therefore, the lowest common multiple of 670,225,745,492,943 is 8472572100.
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.
670 x 225 x 745 x 492 x 943 = 52106318415000
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
745 : 1, 5, 149, 745
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,225,745,492,943, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
225:3x 3x 5x 5
745:5x 149
492:2x 2x 3x 41
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 41 = 6150
Therefore, the value for common factors is 6150.
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 = 52106318415000/(1x6150)
LCM = 52106318415000/6150
LCM = 8472572100
Thus, we can understand that the LCM of 670,225,745,492,943 is 8472572100.
