Given numbers are 987,247,520,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,247,520,437 is 224285880.
Find LCM of 987,247,520,437 with Prime Factorization
13 | 987, 247, 520, 437 |
19 | 987, 19, 40, 437 |
987, 1, 40, 23 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 987 x 1 x 40 x 23 = 224285880
Therefore, the lowest common multiple of 987,247,520,437 is 224285880.
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.
987 x 247 x 520 x 437 = 55398612360
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
247 : 1, 13, 19, 247
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,247,520,437, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
247:13x 19
520:2x 2x 2x 5x 13
437:19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 55398612360/(1x247)
LCM = 55398612360/247
LCM = 224285880
Thus, we can understand that the LCM of 987,247,520,437 is 224285880.
