Given numbers are 653,620,841,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 653,620,841,554 is 94314971020.
Find LCM of 653,620,841,554 with Prime Factorization
| 2 | 653, 620, 841, 554 |
| 653, 310, 841, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 653 x 310 x 841 x 277 = 94314971020
Therefore, the lowest common multiple of 653,620,841,554 is 94314971020.
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.
653 x 620 x 841 x 554 = 188629942040
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.
653 : 1, 653
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
841 : 1, 29, 841
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 653,620,841,554, is 1.
Now, the common factors can be found like this.
653:653
620:2x 2x 5x 31
841:29x 29
554:2x 277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 188629942040/(1x2)
LCM = 188629942040/2
LCM = 94314971020
Thus, we can understand that the LCM of 653,620,841,554 is 94314971020.
