Given numbers are 119,635,561,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 119,635,561,420 is 9974580.
Find LCM of 119,635,561,420 with Prime Factorization
3 | 119, 635, 561, 420 |
5 | 119, 635, 187, 140 |
7 | 119, 127, 187, 28 |
17 | 17, 127, 187, 4 |
1, 127, 11, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 17 x 1 x 127 x 11 x 4 = 9974580
Therefore, the lowest common multiple of 119,635,561,420 is 9974580.
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.
119 x 635 x 561 x 420 = 17804625300
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.
119 : 1, 7, 17, 119
635 : 1, 5, 127, 635
561 : 1, 3, 11, 17, 33, 51, 187, 561
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 119,635,561,420, is 1.
Now, the common factors can be found like this.
119:7x 17
635:5x 127
561:3x 11x 17
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 17 = 1785
Therefore, the value for common factors is 1785.
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 = 17804625300/(1x1785)
LCM = 17804625300/1785
LCM = 9974580
Thus, we can understand that the LCM of 119,635,561,420 is 9974580.
