Find LCM of 647,450,549,854,771 with Prime Factorization
2 | 647, 450, 549, 854, 771 |
3 | 647, 225, 549, 427, 771 |
3 | 647, 75, 183, 427, 257 |
61 | 647, 25, 61, 427, 257 |
647, 25, 1, 7, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 61 x 647 x 25 x 1 x 7 x 257 = 31950509850
Therefore, the lowest common multiple of 647,450,549,854,771 is 31950509850.
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.
647 x 450 x 549 x 854 x 771 = 105244979445900
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.
647 : 1, 647
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
549 : 1, 3, 9, 61, 183, 549
854 : 1, 2, 7, 14, 61, 122, 427, 854
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,450,549,854,771, is 1.
Now, the common factors can be found like this.
647:647
450:2x 3x 3x 5x 5
549:3x 3x 61
854:2x 7x 61
771:3x 257
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 3x 3x 61 = 3294
Therefore, the value for common factors is 3294.
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 = 105244979445900/(1x3294)
LCM = 105244979445900/3294
LCM = 31950509850
Thus, we can understand that the LCM of 647,450,549,854,771 is 31950509850.
