Given numbers are 859,147,931,782,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 859,147,931,782,790 is 741084872430.
Find LCM of 859,147,931,782,790 with Prime Factorization
| 2 | 859, 147, 931, 782, 790 |
| 7 | 859, 147, 931, 391, 395 |
| 7 | 859, 21, 133, 391, 395 |
| 859, 3, 19, 391, 395 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 859 x 3 x 19 x 391 x 395 = 741084872430
Therefore, the lowest common multiple of 859,147,931,782,790 is 741084872430.
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.
859 x 147 x 931 x 782 x 790 = 72626317498140
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.
859 : 1, 859
147 : 1, 3, 7, 21, 49, 147
931 : 1, 7, 19, 49, 133, 931
782 : 1, 2, 17, 23, 34, 46, 391, 782
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 859,147,931,782,790, is 1.
Now, the common factors can be found like this.
859:859
147:3x 7x 7
931:7x 7x 19
782:2x 17x 23
790:2x 5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7 = 98
Therefore, the value for common factors is 98.
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 = 72626317498140/(1x98)
LCM = 72626317498140/98
LCM = 741084872430
Thus, we can understand that the LCM of 859,147,931,782,790 is 741084872430.
