Given numbers are 661,121,770,902,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,121,770,902,894 is 102606825090.
Find LCM of 661,121,770,902,894 with Prime Factorization
| 2 | 661, 121, 770, 902, 894 |
| 11 | 661, 121, 385, 451, 447 |
| 661, 11, 35, 41, 447 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 661 x 11 x 35 x 41 x 447 = 102606825090
Therefore, the lowest common multiple of 661,121,770,902,894 is 102606825090.
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.
661 x 121 x 770 x 902 x 894 = 49661703343560
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.
661 : 1, 661
121 : 1, 11, 121
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
902 : 1, 2, 11, 22, 41, 82, 451, 902
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,121,770,902,894, is 1.
Now, the common factors can be found like this.
661:661
121:11x 11
770:2x 5x 7x 11
902:2x 11x 41
894:2x 3x 149
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 49661703343560/(1x484)
LCM = 49661703343560/484
LCM = 102606825090
Thus, we can understand that the LCM of 661,121,770,902,894 is 102606825090.
