Given numbers are 970,620,430,426,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 970,620,430,426,745 is 82072516740.
Find LCM of 970,620,430,426,745 with Prime Factorization
| 2 | 970, 620, 430, 426, 745 |
| 5 | 485, 310, 215, 213, 745 |
| 97, 62, 43, 213, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 97 x 62 x 43 x 213 x 149 = 82072516740
Therefore, the lowest common multiple of 970,620,430,426,745 is 82072516740.
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.
970 x 620 x 430 x 426 x 745 = 82072516740000
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
430 : 1, 2, 5, 10, 43, 86, 215, 430
426 : 1, 2, 3, 6, 71, 142, 213, 426
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,620,430,426,745, is 1.
Now, the common factors can be found like this.
970:2x 5x 97
620:2x 2x 5x 31
430:2x 5x 43
426:2x 3x 71
745:5x 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 2x 5x 5x 5 = 1000
Therefore, the value for common factors is 1000.
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 = 82072516740000/(1x1000)
LCM = 82072516740000/1000
LCM = 82072516740
Thus, we can understand that the LCM of 970,620,430,426,745 is 82072516740.
