Given numbers are 187,761,221,421,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,761,221,421,143 is 778846211.
Find LCM of 187,761,221,421,143 with Prime Factorization
| 11 | 187, 761, 221, 421, 143 |
| 13 | 17, 761, 221, 421, 13 |
| 17 | 17, 761, 17, 421, 1 |
| 1, 761, 1, 421, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 17 x 1 x 761 x 1 x 421 x 1 = 778846211
Therefore, the lowest common multiple of 187,761,221,421,143 is 778846211.
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 761 x 221 x 421 x 143 = 1893375138941
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
761 : 1, 761
221 : 1, 13, 17, 221
421 : 1, 421
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,761,221,421,143, is 1.
Now, the common factors can be found like this.
187:11x 17
761:761
221:13x 17
421:421
143:11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13x 17 = 2431
Therefore, the value for common factors is 2431.
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 = 1893375138941/(1x2431)
LCM = 1893375138941/2431
LCM = 778846211
Thus, we can understand that the LCM of 187,761,221,421,143 is 778846211.
