Given numbers are 697,638,615,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,638,615,290 is 6670290.
Find LCM of 697,638,615,290 with Prime Factorization
| 2 | 697, 638, 615, 290 |
| 5 | 697, 319, 615, 145 |
| 29 | 697, 319, 123, 29 |
| 41 | 697, 11, 123, 1 |
| 17, 11, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 41 x 17 x 11 x 3 x 1 = 6670290
Therefore, the lowest common multiple of 697,638,615,290 is 6670290.
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.
697 x 638 x 615 x 290 = 79309748100
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.
697 : 1, 17, 41, 697
638 : 1, 2, 11, 22, 29, 58, 319, 638
615 : 1, 3, 5, 15, 41, 123, 205, 615
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,638,615,290, is 1.
Now, the common factors can be found like this.
697:17x 41
638:2x 11x 29
615:3x 5x 41
290:2x 5x 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 5x 29x 41 = 11890
Therefore, the value for common factors is 11890.
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 = 79309748100/(1x11890)
LCM = 79309748100/11890
LCM = 6670290
Thus, we can understand that the LCM of 697,638,615,290 is 6670290.
