Given numbers are 819,121,195,602,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,121,195,602,644 is 1960178220.
Find LCM of 819,121,195,602,644 with Prime Factorization
| 2 | 819, 121, 195, 602, 644 |
| 3 | 819, 121, 195, 301, 322 |
| 7 | 273, 121, 65, 301, 322 |
| 13 | 39, 121, 65, 43, 46 |
| 3, 121, 5, 43, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 3 x 121 x 5 x 43 x 46 = 1960178220
Therefore, the lowest common multiple of 819,121,195,602,644 is 1960178220.
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.
819 x 121 x 195 x 602 x 644 = 7491801156840
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
121 : 1, 11, 121
195 : 1, 3, 5, 13, 15, 39, 65, 195
602 : 1, 2, 7, 14, 43, 86, 301, 602
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,121,195,602,644, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
121:11x 11
195:3x 5x 13
602:2x 7x 43
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7x 13 = 3822
Therefore, the value for common factors is 3822.
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 = 7491801156840/(1x3822)
LCM = 7491801156840/3822
LCM = 1960178220
Thus, we can understand that the LCM of 819,121,195,602,644 is 1960178220.
