Given numbers are 340,763,460,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 340,763,460,621 is 161099820.
Find LCM of 340,763,460,621 with Prime Factorization
2 | 340, 763, 460, 621 |
2 | 170, 763, 230, 621 |
5 | 85, 763, 115, 621 |
23 | 17, 763, 23, 621 |
17, 763, 1, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 17 x 763 x 1 x 27 = 161099820
Therefore, the lowest common multiple of 340,763,460,621 is 161099820.
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.
340 x 763 x 460 x 621 = 74105917200
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
763 : 1, 7, 109, 763
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
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 340,763,460,621, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
763:7x 109
460:2x 2x 5x 23
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.
2x 2x 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 74105917200/(1x460)
LCM = 74105917200/460
LCM = 161099820
Thus, we can understand that the LCM of 340,763,460,621 is 161099820.
