Given numbers are 760,428,870,736
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,428,870,736 is 650885280.
Find LCM of 760,428,870,736 with Prime Factorization
| 2 | 760, 428, 870, 736 |
| 2 | 380, 214, 435, 368 |
| 2 | 190, 107, 435, 184 |
| 5 | 95, 107, 435, 92 |
| 19, 107, 87, 92 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 19 x 107 x 87 x 92 = 650885280
Therefore, the lowest common multiple of 760,428,870,736 is 650885280.
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.
760 x 428 x 870 x 736 = 208283289600
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
428 : 1, 2, 4, 107, 214, 428
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,428,870,736, is 2.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
428:2x 2x 107
870:2x 3x 5x 29
736:2x 2x 2x 2x 2x 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 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 208283289600/(2x160)
LCM = 208283289600/320
LCM = 650885280
Thus, we can understand that the LCM of 760,428,870,736 is 650885280.
