Given numbers are 710,766,760,670,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 710,766,760,670,638 is 441708951640.
Find LCM of 710,766,760,670,638 with Prime Factorization
| 2 | 710, 766, 760, 670, 638 |
| 5 | 355, 383, 380, 335, 319 |
| 71, 383, 76, 67, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 71 x 383 x 76 x 67 x 319 = 441708951640
Therefore, the lowest common multiple of 710,766,760,670,638 is 441708951640.
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.
710 x 766 x 760 x 670 x 638 = 176683580656000
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.
710 : 1, 2, 5, 10, 71, 142, 355, 710
766 : 1, 2, 383, 766
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
670 : 1, 2, 5, 10, 67, 134, 335, 670
638 : 1, 2, 11, 22, 29, 58, 319, 638
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 710,766,760,670,638, is 2.
Now, the common factors can be found like this.
710:2x 5x 71
766:2x 383
760:2x 2x 2x 5x 19
670:2x 5x 67
638:2x 11x 29
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 176683580656000/(2x200)
LCM = 176683580656000/400
LCM = 441708951640
Thus, we can understand that the LCM of 710,766,760,670,638 is 441708951640.
