Given numbers are 524,786,772,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 524,786,772,715 is 216928140.
Find LCM of 524,786,772,715 with Prime Factorization
| 2 | 524, 786, 772, 715 |
| 2 | 262, 393, 386, 715 |
| 131 | 131, 393, 193, 715 |
| 1, 3, 193, 715 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 131 x 1 x 3 x 193 x 715 = 216928140
Therefore, the lowest common multiple of 524,786,772,715 is 216928140.
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.
524 x 786 x 772 x 715 = 227340690720
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.
524 : 1, 2, 4, 131, 262, 524
786 : 1, 2, 3, 6, 131, 262, 393, 786
772 : 1, 2, 4, 193, 386, 772
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,786,772,715, is 1.
Now, the common factors can be found like this.
524:2x 2x 131
786:2x 3x 131
772:2x 2x 193
715:5x 11x 13
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 131 = 1048
Therefore, the value for common factors is 1048.
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 = 227340690720/(1x1048)
LCM = 227340690720/1048
LCM = 216928140
Thus, we can understand that the LCM of 524,786,772,715 is 216928140.
