Given numbers are 817,557,153,602,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 817,557,153,602,782 is 22419429354.
Find LCM of 817,557,153,602,782 with Prime Factorization
2 | 817, 557, 153, 602, 782 |
17 | 817, 557, 153, 301, 391 |
43 | 817, 557, 9, 301, 23 |
19, 557, 9, 7, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 43 x 19 x 557 x 9 x 7 x 23 = 22419429354
Therefore, the lowest common multiple of 817,557,153,602,782 is 22419429354.
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.
817 x 557 x 153 x 602 x 782 = 32777205715548
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.
817 : 1, 19, 43, 817
557 : 1, 557
153 : 1, 3, 9, 17, 51, 153
602 : 1, 2, 7, 14, 43, 86, 301, 602
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,557,153,602,782, is 1.
Now, the common factors can be found like this.
817:19x 43
557:557
153:3x 3x 17
602:2x 7x 43
782:2x 17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 43 = 1462
Therefore, the value for common factors is 1462.
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 = 32777205715548/(1x1462)
LCM = 32777205715548/1462
LCM = 22419429354
Thus, we can understand that the LCM of 817,557,153,602,782 is 22419429354.
