Given numbers are 631,778,602,406,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,778,602,406,774 is 38567008998.
Find LCM of 631,778,602,406,774 with Prime Factorization
| 2 | 631, 778, 602, 406, 774 |
| 7 | 631, 389, 301, 203, 387 |
| 43 | 631, 389, 43, 29, 387 |
| 631, 389, 1, 29, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 43 x 631 x 389 x 1 x 29 x 9 = 38567008998
Therefore, the lowest common multiple of 631,778,602,406,774 is 38567008998.
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.
631 x 778 x 602 x 406 x 774 = 92869357667184
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.
631 : 1, 631
778 : 1, 2, 389, 778
602 : 1, 2, 7, 14, 43, 86, 301, 602
406 : 1, 2, 7, 14, 29, 58, 203, 406
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,778,602,406,774, is 1.
Now, the common factors can be found like this.
631:631
778:2x 389
602:2x 7x 43
406:2x 7x 29
774:2x 3x 3x 43
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 7x 43 = 2408
Therefore, the value for common factors is 2408.
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 = 92869357667184/(1x2408)
LCM = 92869357667184/2408
LCM = 38567008998
Thus, we can understand that the LCM of 631,778,602,406,774 is 38567008998.
