Given numbers are 649,740,715,602,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,740,715,602,814 is 1879257380.
Find LCM of 649,740,715,602,814 with Prime Factorization
| 2 | 649, 740, 715, 602, 814 |
| 5 | 649, 370, 715, 301, 407 |
| 11 | 649, 74, 143, 301, 407 |
| 37 | 59, 74, 13, 301, 37 |
| 59, 2, 13, 301, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 37 x 59 x 2 x 13 x 301 x 1 = 1879257380
Therefore, the lowest common multiple of 649,740,715,602,814 is 1879257380.
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.
649 x 740 x 715 x 602 x 814 = 168268705805200
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.
649 : 1, 11, 59, 649
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
715 : 1, 5, 11, 13, 55, 65, 143, 715
602 : 1, 2, 7, 14, 43, 86, 301, 602
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,740,715,602,814, is 1.
Now, the common factors can be found like this.
649:11x 59
740:2x 2x 5x 37
715:5x 11x 13
602:2x 7x 43
814:2x 11x 37
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 5x 11x 11x 37 = 89540
Therefore, the value for common factors is 89540.
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 = 168268705805200/(1x89540)
LCM = 168268705805200/89540
LCM = 1879257380
Thus, we can understand that the LCM of 649,740,715,602,814 is 1879257380.
