Given numbers are 874,782,609,224
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 874,782,609,224 is 144776352.
Find LCM of 874,782,609,224 with Prime Factorization
2 | 874, 782, 609, 224 |
7 | 437, 391, 609, 112 |
23 | 437, 391, 87, 16 |
19, 17, 87, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 19 x 17 x 87 x 16 = 144776352
Therefore, the lowest common multiple of 874,782,609,224 is 144776352.
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.
874 x 782 x 609 x 224 = 93235970688
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
782 : 1, 2, 17, 23, 34, 46, 391, 782
609 : 1, 3, 7, 21, 29, 87, 203, 609
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,782,609,224, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
782:2x 17x 23
609:3x 7x 29
224:2x 2x 2x 2x 2x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7x 23 = 644
Therefore, the value for common factors is 644.
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 = 93235970688/(1x644)
LCM = 93235970688/644
LCM = 144776352
Thus, we can understand that the LCM of 874,782,609,224 is 144776352.
