Given numbers are 157,817,358,551,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,817,358,551,989 is 30628841434.
Find LCM of 157,817,358,551,989 with Prime Factorization
19 | 157, 817, 358, 551, 989 |
43 | 157, 43, 358, 29, 989 |
157, 1, 358, 29, 23 |
Multiply the prime numbers at the bottom and the left side.
19 x 43 x 157 x 1 x 358 x 29 x 23 = 30628841434
Therefore, the lowest common multiple of 157,817,358,551,989 is 30628841434.
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.
157 x 817 x 358 x 551 x 989 = 25023763451578
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.
157 : 1, 157
817 : 1, 19, 43, 817
358 : 1, 2, 179, 358
551 : 1, 19, 29, 551
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,817,358,551,989, is 1.
Now, the common factors can be found like this.
157:157
817:19x 43
358:2x 179
551:19x 29
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 43 = 817
Therefore, the value for common factors is 817.
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 = 25023763451578/(1x817)
LCM = 25023763451578/817
LCM = 30628841434
Thus, we can understand that the LCM of 157,817,358,551,989 is 30628841434.
