Given numbers are 513,639,707,281,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,639,707,281,909 is 7236048141.
Find LCM of 513,639,707,281,909 with Prime Factorization
3 | 513, 639, 707, 281, 909 |
3 | 171, 213, 707, 281, 303 |
101 | 57, 71, 707, 281, 101 |
57, 71, 7, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 101 x 57 x 71 x 7 x 281 x 1 = 7236048141
Therefore, the lowest common multiple of 513,639,707,281,909 is 7236048141.
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.
513 x 639 x 707 x 281 x 909 = 59198109841521
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
639 : 1, 3, 9, 71, 213, 639
707 : 1, 7, 101, 707
281 : 1, 281
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,639,707,281,909, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
639:3x 3x 71
707:7x 101
281:281
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 101 = 8181
Therefore, the value for common factors is 8181.
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 = 59198109841521/(1x8181)
LCM = 59198109841521/8181
LCM = 7236048141
Thus, we can understand that the LCM of 513,639,707,281,909 is 7236048141.
