Given numbers are 980,680,905,602
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,680,905,602 is 259329560.
Find LCM of 980,680,905,602 with Prime Factorization
| 2 | 980, 680, 905, 602 |
| 2 | 490, 340, 905, 301 |
| 5 | 245, 170, 905, 301 |
| 7 | 49, 34, 181, 301 |
| 7, 34, 181, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 7 x 34 x 181 x 43 = 259329560
Therefore, the lowest common multiple of 980,680,905,602 is 259329560.
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 680 x 905 x 602 = 363061384000
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
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
905 : 1, 5, 181, 905
602 : 1, 2, 7, 14, 43, 86, 301, 602
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,680,905,602, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
680:2x 2x 2x 5x 17
905:5x 181
602:2x 7x 43
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 = 363061384000/(1x1400)
LCM = 363061384000/1400
LCM = 259329560
Thus, we can understand that the LCM of 980,680,905,602 is 259329560.
