Given numbers are 724,578,506,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,578,506,644 is 370556956.
Find LCM of 724,578,506,644 with Prime Factorization
| 2 | 724, 578, 506, 644 |
| 2 | 362, 289, 253, 322 |
| 23 | 181, 289, 253, 161 |
| 181, 289, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 181 x 289 x 11 x 7 = 370556956
Therefore, the lowest common multiple of 724,578,506,644 is 370556956.
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.
724 x 578 x 506 x 644 = 136364959808
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.
724 : 1, 2, 4, 181, 362, 724
578 : 1, 2, 17, 34, 289, 578
506 : 1, 2, 11, 22, 23, 46, 253, 506
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,578,506,644, is 2.
Now, the common factors can be found like this.
724:2x 2x 181
578:2x 17x 17
506:2x 11x 23
644:2x 2x 7x 23
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 23 = 184
Therefore, the value for common factors is 184.
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 = 136364959808/(2x184)
LCM = 136364959808/368
LCM = 370556956
Thus, we can understand that the LCM of 724,578,506,644 is 370556956.
