Find LCM of 321,748,644,875,616 with Prime Factorization
2 | 321, 748, 644, 875, 616 |
2 | 321, 374, 322, 875, 308 |
7 | 321, 187, 161, 875, 154 |
11 | 321, 187, 23, 125, 22 |
321, 17, 23, 125, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 321 x 17 x 23 x 125 x 2 = 9664347000
Therefore, the lowest common multiple of 321,748,644,875,616 is 9664347000.
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.
321 x 748 x 644 x 875 x 616 = 83345328528000
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.
321 : 1, 3, 107, 321
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
875 : 1, 5, 7, 25, 35, 125, 175, 875
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,748,644,875,616, is 1.
Now, the common factors can be found like this.
321:3x 107
748:2x 2x 11x 17
644:2x 2x 7x 23
875:5x 5x 5x 7
616:2x 2x 2x 7x 11
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 7x 7x 11 = 8624
Therefore, the value for common factors is 8624.
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 = 83345328528000/(1x8624)
LCM = 83345328528000/8624
LCM = 9664347000
Thus, we can understand that the LCM of 321,748,644,875,616 is 9664347000.
