Given numbers are 721,464,126,863,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,464,126,863,615 is 532672665840.
Find LCM of 721,464,126,863,615 with Prime Factorization
| 2 | 721, 464, 126, 863, 615 |
| 3 | 721, 232, 63, 863, 615 |
| 7 | 721, 232, 21, 863, 205 |
| 103, 232, 3, 863, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 103 x 232 x 3 x 863 x 205 = 532672665840
Therefore, the lowest common multiple of 721,464,126,863,615 is 532672665840.
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.
721 x 464 x 126 x 863 x 615 = 22372251965280
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.
721 : 1, 7, 103, 721
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
863 : 1, 863
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,464,126,863,615, is 1.
Now, the common factors can be found like this.
721:7x 103
464:2x 2x 2x 2x 29
126:2x 3x 3x 7
863:863
615:3x 5x 41
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 7 = 42
Therefore, the value for common factors is 42.
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 = 22372251965280/(1x42)
LCM = 22372251965280/42
LCM = 532672665840
Thus, we can understand that the LCM of 721,464,126,863,615 is 532672665840.
