Given numbers are 921,758,842,626,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,758,842,626,680 is 31277655092760.
Find LCM of 921,758,842,626,680 with Prime Factorization
2 | 921, 758, 842, 626, 680 |
921, 379, 421, 313, 340 |
Multiply the prime numbers at the bottom and the left side.
2 x 921 x 379 x 421 x 313 x 340 = 31277655092760
Therefore, the lowest common multiple of 921,758,842,626,680 is 31277655092760.
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.
921 x 758 x 842 x 626 x 680 = 250221240742080
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.
921 : 1, 3, 307, 921
758 : 1, 2, 379, 758
842 : 1, 2, 421, 842
626 : 1, 2, 313, 626
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,758,842,626,680, is 1.
Now, the common factors can be found like this.
921:3x 307
758:2x 379
842:2x 421
626:2x 313
680:2x 2x 2x 5x 17
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 = 250221240742080/(1x8)
LCM = 250221240742080/8
LCM = 31277655092760
Thus, we can understand that the LCM of 921,758,842,626,680 is 31277655092760.
