Given numbers are 187,784,238,564
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,784,238,564 is 20671728.
Find LCM of 187,784,238,564 with Prime Factorization
2 | 187, 784, 238, 564 |
2 | 187, 392, 119, 282 |
7 | 187, 196, 119, 141 |
17 | 187, 28, 17, 141 |
11, 28, 1, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 17 x 11 x 28 x 1 x 141 = 20671728
Therefore, the lowest common multiple of 187,784,238,564 is 20671728.
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.
187 x 784 x 238 x 564 = 19679485056
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.
187 : 1, 11, 17, 187
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
238 : 1, 2, 7, 14, 17, 34, 119, 238
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,784,238,564, is 1.
Now, the common factors can be found like this.
187:11x 17
784:2x 2x 2x 2x 7x 7
238:2x 7x 17
564:2x 2x 3x 47
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 7x 17 = 952
Therefore, the value for common factors is 952.
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 = 19679485056/(1x952)
LCM = 19679485056/952
LCM = 20671728
Thus, we can understand that the LCM of 187,784,238,564 is 20671728.
