5 | 661, 115, 817, 10, 29 |
661, 23, 817, 2, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 661 x 23 x 817 x 2 x 29 = 172898245920
Therefore, the lowest common multiple of 661,690,817,480,464 is 172898245920.
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.
661 x 690 x 817 x 480 x 464 = 82991158041600
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.
661 : 1, 661
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
817 : 1, 19, 43, 817
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,690,817,480,464, is 1.
Now, the common factors can be found like this.
661:661
690:2x 3x 5x 23
817:19x 43
480:2x 2x 2x 2x 2x 3x 5
464:2x 2x 2x 2x 29
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 2x 2x 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 82991158041600/(1x480)
LCM = 82991158041600/480
LCM = 172898245920
Thus, we can understand that the LCM of 661,690,817,480,464 is 172898245920.
