Given numbers are 577,770,164,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 577,770,164,620 is 1129385180.
Find LCM of 577,770,164,620 with Prime Factorization
2 | 577, 770, 164, 620 |
2 | 577, 385, 82, 310 |
5 | 577, 385, 41, 155 |
577, 77, 41, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 577 x 77 x 41 x 31 = 1129385180
Therefore, the lowest common multiple of 577,770,164,620 is 1129385180.
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.
577 x 770 x 164 x 620 = 45175407200
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.
577 : 1, 577
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
164 : 1, 2, 4, 41, 82, 164
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,770,164,620, is 1.
Now, the common factors can be found like this.
577:577
770:2x 5x 7x 11
164:2x 2x 41
620:2x 2x 5x 31
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 5 = 40
Therefore, the value for common factors is 40.
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 = 45175407200/(1x40)
LCM = 45175407200/40
LCM = 1129385180
Thus, we can understand that the LCM of 577,770,164,620 is 1129385180.
