Given numbers are 671,838,931,180,763
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,838,931,180,763 is 5135529486780.
Find LCM of 671,838,931,180,763 with Prime Factorization
2 | 671, 838, 931, 180, 763 |
7 | 671, 419, 931, 90, 763 |
671, 419, 133, 90, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 671 x 419 x 133 x 90 x 109 = 5135529486780
Therefore, the lowest common multiple of 671,838,931,180,763 is 5135529486780.
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.
671 x 838 x 931 x 180 x 763 = 71897412814920
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.
671 : 1, 11, 61, 671
838 : 1, 2, 419, 838
931 : 1, 7, 19, 49, 133, 931
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,838,931,180,763, is 1.
Now, the common factors can be found like this.
671:11x 61
838:2x 419
931:7x 7x 19
180:2x 2x 3x 3x 5
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 71897412814920/(1x14)
LCM = 71897412814920/14
LCM = 5135529486780
Thus, we can understand that the LCM of 671,838,931,180,763 is 5135529486780.
