Given numbers are 875,628,548,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 875,628,548,639 is 48104878500.
Find LCM of 875,628,548,639 with Prime Factorization
| 2 | 875, 628, 548, 639 |
| 2 | 875, 314, 274, 639 |
| 875, 157, 137, 639 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 875 x 157 x 137 x 639 = 48104878500
Therefore, the lowest common multiple of 875,628,548,639 is 48104878500.
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.
875 x 628 x 548 x 639 = 192419514000
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.
875 : 1, 5, 7, 25, 35, 125, 175, 875
628 : 1, 2, 4, 157, 314, 628
548 : 1, 2, 4, 137, 274, 548
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,628,548,639, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
628:2x 2x 157
548:2x 2x 137
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 192419514000/(1x4)
LCM = 192419514000/4
LCM = 48104878500
Thus, we can understand that the LCM of 875,628,548,639 is 48104878500.
