Given numbers are 453,780,721,906
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,780,721,906 is 84919380.
Find LCM of 453,780,721,906 with Prime Factorization
2 | 453, 780, 721, 906 |
3 | 453, 390, 721, 453 |
151 | 151, 130, 721, 151 |
1, 130, 721, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 151 x 1 x 130 x 721 x 1 = 84919380
Therefore, the lowest common multiple of 453,780,721,906 is 84919380.
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.
453 x 780 x 721 x 906 = 230810874840
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.
453 : 1, 3, 151, 453
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
721 : 1, 7, 103, 721
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,780,721,906, is 1.
Now, the common factors can be found like this.
453:3x 151
780:2x 2x 3x 5x 13
721:7x 103
906:2x 3x 151
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 3x 151 = 2718
Therefore, the value for common factors is 2718.
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 = 230810874840/(1x2718)
LCM = 230810874840/2718
LCM = 84919380
Thus, we can understand that the LCM of 453,780,721,906 is 84919380.
