Given numbers are 507,907,639,738,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,907,639,738,621 is 554188861746.
Find LCM of 507,907,639,738,621 with Prime Factorization
3 | 507, 907, 639, 738, 621 |
3 | 169, 907, 213, 246, 207 |
169, 907, 71, 82, 69 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 169 x 907 x 71 x 82 x 69 = 554188861746
Therefore, the lowest common multiple of 507,907,639,738,621 is 554188861746.
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.
507 x 907 x 639 x 738 x 621 = 134667893404278
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.
507 : 1, 3, 13, 39, 169, 507
907 : 1, 907
639 : 1, 3, 9, 71, 213, 639
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,907,639,738,621, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
907:907
639:3x 3x 71
738:2x 3x 3x 41
621:3x 3x 3x 23
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 3 = 243
Therefore, the value for common factors is 243.
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 = 134667893404278/(1x243)
LCM = 134667893404278/243
LCM = 554188861746
Thus, we can understand that the LCM of 507,907,639,738,621 is 554188861746.
