Given numbers are 698,148,436,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,148,436,638 is 1795991692.
Find LCM of 698,148,436,638 with Prime Factorization
2 | 698, 148, 436, 638 |
2 | 349, 74, 218, 319 |
349, 37, 109, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 349 x 37 x 109 x 319 = 1795991692
Therefore, the lowest common multiple of 698,148,436,638 is 1795991692.
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.
698 x 148 x 436 x 638 = 28735867072
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.
698 : 1, 2, 349, 698
148 : 1, 2, 4, 37, 74, 148
436 : 1, 2, 4, 109, 218, 436
638 : 1, 2, 11, 22, 29, 58, 319, 638
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,148,436,638, is 2.
Now, the common factors can be found like this.
698:2x 349
148:2x 2x 37
436:2x 2x 109
638:2x 11x 29
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 2 = 8
Therefore, the value for common factors is 8.
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 = 28735867072/(2x8)
LCM = 28735867072/16
LCM = 1795991692
Thus, we can understand that the LCM of 698,148,436,638 is 1795991692.
