Given numbers are 931,382,221,371
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,382,221,371 is 4165634746.
Find LCM of 931,382,221,371 with Prime Factorization
7 | 931, 382, 221, 371 |
133, 382, 221, 53 |
Multiply the prime numbers at the bottom and the left side.
7 x 133 x 382 x 221 x 53 = 4165634746
Therefore, the lowest common multiple of 931,382,221,371 is 4165634746.
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.
931 x 382 x 221 x 371 = 29159443222
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.
931 : 1, 7, 19, 49, 133, 931
382 : 1, 2, 191, 382
221 : 1, 13, 17, 221
371 : 1, 7, 53, 371
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,382,221,371, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
382:2x 191
221:13x 17
371:7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 29159443222/(1x7)
LCM = 29159443222/7
LCM = 4165634746
Thus, we can understand that the LCM of 931,382,221,371 is 4165634746.
