Given numbers are 427,819,671,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,819,671,641 is 352260909.
Find LCM of 427,819,671,641 with Prime Factorization
| 7 | 427, 819, 671, 641 |
| 61 | 61, 117, 671, 641 |
| 1, 117, 11, 641 |
Multiply the prime numbers at the bottom and the left side.
7 x 61 x 1 x 117 x 11 x 641 = 352260909
Therefore, the lowest common multiple of 427,819,671,641 is 352260909.
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.
427 x 819 x 671 x 641 = 150415408143
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.
427 : 1, 7, 61, 427
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
671 : 1, 11, 61, 671
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,819,671,641, is 1.
Now, the common factors can be found like this.
427:7x 61
819:3x 3x 7x 13
671:11x 61
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 61 = 427
Therefore, the value for common factors is 427.
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 = 150415408143/(1x427)
LCM = 150415408143/427
LCM = 352260909
Thus, we can understand that the LCM of 427,819,671,641 is 352260909.
