Given numbers are 902,616,668,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,616,668,988 is 1041784744.
Find LCM of 902,616,668,988 with Prime Factorization
| 2 | 902, 616, 668, 988 |
| 2 | 451, 308, 334, 494 |
| 11 | 451, 154, 167, 247 |
| 41, 14, 167, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 41 x 14 x 167 x 247 = 1041784744
Therefore, the lowest common multiple of 902,616,668,988 is 1041784744.
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.
902 x 616 x 668 x 988 = 366708229888
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
668 : 1, 2, 4, 167, 334, 668
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,616,668,988, is 2.
Now, the common factors can be found like this.
902:2x 11x 41
616:2x 2x 2x 7x 11
668:2x 2x 167
988:2x 2x 13x 19
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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 366708229888/(2x176)
LCM = 366708229888/352
LCM = 1041784744
Thus, we can understand that the LCM of 902,616,668,988 is 1041784744.
