Given numbers are 154,142,861,779,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,142,861,779,802 is 10246655958.
Find LCM of 154,142,861,779,802 with Prime Factorization
| 2 | 154, 142, 861, 779, 802 |
| 7 | 77, 71, 861, 779, 401 |
| 41 | 11, 71, 123, 779, 401 |
| 11, 71, 3, 19, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 11 x 71 x 3 x 19 x 401 = 10246655958
Therefore, the lowest common multiple of 154,142,861,779,802 is 10246655958.
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.
154 x 142 x 861 x 779 x 802 = 11763161039784
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
142 : 1, 2, 71, 142
861 : 1, 3, 7, 21, 41, 123, 287, 861
779 : 1, 19, 41, 779
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,142,861,779,802, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
142:2x 71
861:3x 7x 41
779:19x 41
802:2x 401
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 7x 41 = 1148
Therefore, the value for common factors is 1148.
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 = 11763161039784/(1x1148)
LCM = 11763161039784/1148
LCM = 10246655958
Thus, we can understand that the LCM of 154,142,861,779,802 is 10246655958.
