Given numbers are 678,700,902,779,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,700,902,779,790 is 160640472300.
Find LCM of 678,700,902,779,790 with Prime Factorization
| 2 | 678, 700, 902, 779, 790 |
| 5 | 339, 350, 451, 779, 395 |
| 41 | 339, 70, 451, 779, 79 |
| 339, 70, 11, 19, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 41 x 339 x 70 x 11 x 19 x 79 = 160640472300
Therefore, the lowest common multiple of 678,700,902,779,790 is 160640472300.
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.
678 x 700 x 902 x 779 x 790 = 263450374572000
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
902 : 1, 2, 11, 22, 41, 82, 451, 902
779 : 1, 19, 41, 779
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 678,700,902,779,790, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
700:2x 2x 5x 5x 7
902:2x 11x 41
779:19x 41
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 2x 2x 5x 41 = 1640
Therefore, the value for common factors is 1640.
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 = 263450374572000/(1x1640)
LCM = 263450374572000/1640
LCM = 160640472300
Thus, we can understand that the LCM of 678,700,902,779,790 is 160640472300.
