Given numbers are 442,658,770,533,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,658,770,533,971 is 318407979890.
Find LCM of 442,658,770,533,971 with Prime Factorization
| 2 | 442, 658, 770, 533, 971 |
| 7 | 221, 329, 385, 533, 971 |
| 13 | 221, 47, 55, 533, 971 |
| 17, 47, 55, 41, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 17 x 47 x 55 x 41 x 971 = 318407979890
Therefore, the lowest common multiple of 442,658,770,533,971 is 318407979890.
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.
442 x 658 x 770 x 533 x 971 = 115900504679960
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
658 : 1, 2, 7, 14, 47, 94, 329, 658
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
533 : 1, 13, 41, 533
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,658,770,533,971, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
658:2x 7x 47
770:2x 5x 7x 11
533:13x 41
971:971
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 13 = 364
Therefore, the value for common factors is 364.
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 = 115900504679960/(1x364)
LCM = 115900504679960/364
LCM = 318407979890
Thus, we can understand that the LCM of 442,658,770,533,971 is 318407979890.
