Given numbers are 842,991,612,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,991,612,572 is 36512637876.
Find LCM of 842,991,612,572 with Prime Factorization
2 | 842, 991, 612, 572 |
2 | 421, 991, 306, 286 |
421, 991, 153, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 421 x 991 x 153 x 143 = 36512637876
Therefore, the lowest common multiple of 842,991,612,572 is 36512637876.
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.
842 x 991 x 612 x 572 = 292101103008
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.
842 : 1, 2, 421, 842
991 : 1, 991
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,991,612,572, is 1.
Now, the common factors can be found like this.
842:2x 421
991:991
612:2x 2x 3x 3x 17
572:2x 2x 11x 13
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 2 = 8
Therefore, the value for common factors is 8.
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 = 292101103008/(1x8)
LCM = 292101103008/8
LCM = 36512637876
Thus, we can understand that the LCM of 842,991,612,572 is 36512637876.
