Given numbers are 103,520,971,702,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,520,971,702,862 is 605202666120.
Find LCM of 103,520,971,702,862 with Prime Factorization
| 2 | 103, 520, 971, 702, 862 |
| 13 | 103, 260, 971, 351, 431 |
| 103, 20, 971, 27, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 103 x 20 x 971 x 27 x 431 = 605202666120
Therefore, the lowest common multiple of 103,520,971,702,862 is 605202666120.
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.
103 x 520 x 971 x 702 x 862 = 31470538638240
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.
103 : 1, 103
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
971 : 1, 971
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,520,971,702,862, is 1.
Now, the common factors can be found like this.
103:103
520:2x 2x 2x 5x 13
971:971
702:2x 3x 3x 3x 13
862:2x 431
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 13 = 52
Therefore, the value for common factors is 52.
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 = 31470538638240/(1x52)
LCM = 31470538638240/52
LCM = 605202666120
Thus, we can understand that the LCM of 103,520,971,702,862 is 605202666120.
