Given numbers are 817,894,986,517,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,894,986,517,972 is 30158660767356.
Find LCM of 817,894,986,517,972 with Prime Factorization
| 2 | 817, 894, 986, 517, 972 |
| 3 | 817, 447, 493, 517, 486 |
| 817, 149, 493, 517, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 817 x 149 x 493 x 517 x 162 = 30158660767356
Therefore, the lowest common multiple of 817,894,986,517,972 is 30158660767356.
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.
817 x 894 x 986 x 517 x 972 = 361903929208272
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.
817 : 1, 19, 43, 817
894 : 1, 2, 3, 6, 149, 298, 447, 894
986 : 1, 2, 17, 29, 34, 58, 493, 986
517 : 1, 11, 47, 517
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,894,986,517,972, is 1.
Now, the common factors can be found like this.
817:19x 43
894:2x 3x 149
986:2x 17x 29
517:11x 47
972:2x 2x 3x 3x 3x 3x 3
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 3 = 12
Therefore, the value for common factors is 12.
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 = 361903929208272/(1x12)
LCM = 361903929208272/12
LCM = 30158660767356
Thus, we can understand that the LCM of 817,894,986,517,972 is 30158660767356.
