Given numbers are 822,785,679,515,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,785,679,515,628 is 90256495980.
Find LCM of 822,785,679,515,628 with Prime Factorization
| 2 | 822, 785, 679, 515, 628 |
| 5 | 411, 785, 679, 515, 314 |
| 157 | 411, 157, 679, 103, 314 |
| 411, 1, 679, 103, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 157 x 411 x 1 x 679 x 103 x 2 = 90256495980
Therefore, the lowest common multiple of 822,785,679,515,628 is 90256495980.
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.
822 x 785 x 679 x 515 x 628 = 141702698688600
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
785 : 1, 5, 157, 785
679 : 1, 7, 97, 679
515 : 1, 5, 103, 515
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,785,679,515,628, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
785:5x 157
679:7x 97
515:5x 103
628:2x 2x 157
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 157 = 1570
Therefore, the value for common factors is 1570.
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 = 141702698688600/(1x1570)
LCM = 141702698688600/1570
LCM = 90256495980
Thus, we can understand that the LCM of 822,785,679,515,628 is 90256495980.
