Given numbers are 320,749,771,618,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 320,749,771,618,892 is 4244516848320.
Find LCM of 320,749,771,618,892 with Prime Factorization
| 2 | 320, 749, 771, 618, 892 |
| 2 | 160, 749, 771, 309, 446 |
| 3 | 80, 749, 771, 309, 223 |
| 80, 749, 257, 103, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 80 x 749 x 257 x 103 x 223 = 4244516848320
Therefore, the lowest common multiple of 320,749,771,618,892 is 4244516848320.
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.
320 x 749 x 771 x 618 x 892 = 101868404359680
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
749 : 1, 7, 107, 749
771 : 1, 3, 257, 771
618 : 1, 2, 3, 6, 103, 206, 309, 618
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,749,771,618,892, is 1.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
749:7x 107
771:3x 257
618:2x 3x 103
892:2x 2x 223
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 3 = 24
Therefore, the value for common factors is 24.
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 = 101868404359680/(1x24)
LCM = 101868404359680/24
LCM = 4244516848320
Thus, we can understand that the LCM of 320,749,771,618,892 is 4244516848320.
