Given numbers are 790,790,862,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,790,862,971 is 330615790.
Find LCM of 790,790,862,971 with Prime Factorization
| 2 | 790, 790, 862, 971 |
| 5 | 395, 395, 431, 971 |
| 79 | 79, 79, 431, 971 |
| 1, 1, 431, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 1 x 1 x 431 x 971 = 330615790
Therefore, the lowest common multiple of 790,790,862,971 is 330615790.
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.
790 x 790 x 862 x 971 = 522372948200
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
790 : 1, 2, 5, 10, 79, 158, 395, 790
862 : 1, 2, 431, 862
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,790,862,971, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
790:2x 5x 79
862:2x 431
971:971
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 5x 79 = 1580
Therefore, the value for common factors is 1580.
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 = 522372948200/(1x1580)
LCM = 522372948200/1580
LCM = 330615790
Thus, we can understand that the LCM of 790,790,862,971 is 330615790.
