Given numbers are 406,680,417,769,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,680,417,769,663 is 575454111960.
Find LCM of 406,680,417,769,663 with Prime Factorization
2 | 406, 680, 417, 769, 663 |
3 | 203, 340, 417, 769, 663 |
17 | 203, 340, 139, 769, 221 |
203, 20, 139, 769, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 203 x 20 x 139 x 769 x 13 = 575454111960
Therefore, the lowest common multiple of 406,680,417,769,663 is 575454111960.
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.
406 x 680 x 417 x 769 x 663 = 58696319419920
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
417 : 1, 3, 139, 417
769 : 1, 769
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,680,417,769,663, is 1.
Now, the common factors can be found like this.
406:2x 7x 29
680:2x 2x 2x 5x 17
417:3x 139
769:769
663:3x 13x 17
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 17 = 102
Therefore, the value for common factors is 102.
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 = 58696319419920/(1x102)
LCM = 58696319419920/102
LCM = 575454111960
Thus, we can understand that the LCM of 406,680,417,769,663 is 575454111960.
