Given numbers are 718,214,749,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 718,214,749,628 is 168863548.
Find LCM of 718,214,749,628 with Prime Factorization
| 2 | 718, 214, 749, 628 |
| 107 | 359, 107, 749, 314 |
| 359, 1, 7, 314 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 359 x 1 x 7 x 314 = 168863548
Therefore, the lowest common multiple of 718,214,749,628 is 168863548.
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.
718 x 214 x 749 x 628 = 72273598544
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.
718 : 1, 2, 359, 718
214 : 1, 2, 107, 214
749 : 1, 7, 107, 749
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,214,749,628, is 1.
Now, the common factors can be found like this.
718:2x 359
214:2x 107
749:7x 107
628:2x 2x 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 107 = 428
Therefore, the value for common factors is 428.
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 = 72273598544/(1x428)
LCM = 72273598544/428
LCM = 168863548
Thus, we can understand that the LCM of 718,214,749,628 is 168863548.
