The LCM of 160,435,840,757 is 73762080.
Find LCM of 160,435,840,757 with Prime Factorization
| 2 | 160, 435, 840, 757 |
| 2 | 80, 435, 420, 757 |
| 2 | 40, 435, 210, 757 |
| 3 | 20, 435, 105, 757 |
| 5 | 20, 145, 35, 757 |
| 4, 29, 7, 757 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 4 x 29 x 7 x 757 = 73762080
Therefore, the lowest common multiple of 160,435,840,757 is 73762080.
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.
160 x 435 x 840 x 757 = 44257248000
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.
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
435 : 1, 3, 5, 15, 29, 87, 145, 435
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
757 : 1, 757
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,435,840,757, is 1.
Now, the common factors can be found like this.
160:2x 2x 2x 2x 2x 5
435:3x 5x 29
840:2x 2x 2x 3x 5x 7
757:757
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 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 44257248000/(1x600)
LCM = 44257248000/600
LCM = 73762080
Thus, we can understand that the LCM of 160,435,840,757 is 73762080.
