| 7 | 107, 7, 77, 2, 31 |
| 107, 1, 11, 2, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 7 x 107 x 1 x 11 x 2 x 31 = 110336688
Therefore, the lowest common multiple of 321,189,616,432,372 is 110336688.
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 189 x 616 x 432 x 372 = 6005846601216
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
189 : 1, 3, 7, 9, 21, 27, 63, 189
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,189,616,432,372, is 1.
Now, the common factors can be found like this.
321:3x 107
189:3x 3x 3x 7
616:2x 2x 2x 7x 11
432:2x 2x 2x 2x 3x 3x 3
372:2x 2x 3x 31
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 3x 3x 3x 3x 7 = 54432
Therefore, the value for common factors is 54432.
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 = 6005846601216/(1x54432)
LCM = 6005846601216/54432
LCM = 110336688
Thus, we can understand that the LCM of 321,189,616,432,372 is 110336688.
