Given numbers are 955,978,740,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 955,978,740,661 is 45685186860.
Find LCM of 955,978,740,661 with Prime Factorization
2 | 955, 978, 740, 661 |
5 | 955, 489, 370, 661 |
191, 489, 74, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 191 x 489 x 74 x 661 = 45685186860
Therefore, the lowest common multiple of 955,978,740,661 is 45685186860.
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.
955 x 978 x 740 x 661 = 456851868600
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.
955 : 1, 5, 191, 955
978 : 1, 2, 3, 6, 163, 326, 489, 978
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,978,740,661, is 1.
Now, the common factors can be found like this.
955:5x 191
978:2x 3x 163
740:2x 2x 5x 37
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 456851868600/(1x10)
LCM = 456851868600/10
LCM = 45685186860
Thus, we can understand that the LCM of 955,978,740,661 is 45685186860.
