Given numbers are 980,670,515,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,670,515,308 is 74392780.
Find LCM of 980,670,515,308 with Prime Factorization
2 | 980, 670, 515, 308 |
2 | 490, 335, 515, 154 |
5 | 245, 335, 515, 77 |
7 | 49, 67, 103, 77 |
7, 67, 103, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 7 x 67 x 103 x 11 = 74392780
Therefore, the lowest common multiple of 980,670,515,308 is 74392780.
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.
980 x 670 x 515 x 308 = 104149892000
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
670 : 1, 2, 5, 10, 67, 134, 335, 670
515 : 1, 5, 103, 515
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,670,515,308, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
670:2x 5x 67
515:5x 103
308:2x 2x 7x 11
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 5x 5x 7 = 1400
Therefore, the value for common factors is 1400.
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 = 104149892000/(1x1400)
LCM = 104149892000/1400
LCM = 74392780
Thus, we can understand that the LCM of 980,670,515,308 is 74392780.
