Given numbers are 749,836,817,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,836,817,361 is 511575988.
Find LCM of 749,836,817,361 with Prime Factorization
| 19 | 749, 836, 817, 361 |
| 749, 44, 43, 19 |
Multiply the prime numbers at the bottom and the left side.
19 x 749 x 44 x 43 x 19 = 511575988
Therefore, the lowest common multiple of 749,836,817,361 is 511575988.
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.
749 x 836 x 817 x 361 = 184678931668
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.
749 : 1, 7, 107, 749
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
817 : 1, 19, 43, 817
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,836,817,361, is 1.
Now, the common factors can be found like this.
749:7x 107
836:2x 2x 11x 19
817:19x 43
361:19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 19 = 361
Therefore, the value for common factors is 361.
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 = 184678931668/(1x361)
LCM = 184678931668/361
LCM = 511575988
Thus, we can understand that the LCM of 749,836,817,361 is 511575988.
