Find LCM of 945,157,460,636,942 with Prime Factorization
| 2 | 945, 157, 460, 636, 942 |
| 2 | 945, 157, 230, 318, 471 |
| 3 | 945, 157, 115, 159, 471 |
| 5 | 315, 157, 115, 53, 157 |
| 157 | 63, 157, 23, 53, 157 |
| 63, 1, 23, 53, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 157 x 63 x 1 x 23 x 53 x 1 = 723427740
Therefore, the lowest common multiple of 945,157,460,636,942 is 723427740.
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.
945 x 157 x 460 x 636 x 942 = 40888135864800
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
157 : 1, 157
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,157,460,636,942, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
157:157
460:2x 2x 5x 23
636:2x 2x 3x 53
942:2x 3x 157
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 3x 3x 5x 157 = 56520
Therefore, the value for common factors is 56520.
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 = 40888135864800/(1x56520)
LCM = 40888135864800/56520
LCM = 723427740
Thus, we can understand that the LCM of 945,157,460,636,942 is 723427740.
