Given numbers are 590,842,140,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 590,842,140,972 is 845022780.
Find LCM of 590,842,140,972 with Prime Factorization
| 2 | 590, 842, 140, 972 |
| 2 | 295, 421, 70, 486 |
| 5 | 295, 421, 35, 243 |
| 59, 421, 7, 243 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 59 x 421 x 7 x 243 = 845022780
Therefore, the lowest common multiple of 590,842,140,972 is 845022780.
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.
590 x 842 x 140 x 972 = 67601822400
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.
590 : 1, 2, 5, 10, 59, 118, 295, 590
842 : 1, 2, 421, 842
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 590,842,140,972, is 2.
Now, the common factors can be found like this.
590:2x 5x 59
842:2x 421
140:2x 2x 5x 7
972:2x 2x 3x 3x 3x 3x 3
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 = 67601822400/(2x40)
LCM = 67601822400/80
LCM = 845022780
Thus, we can understand that the LCM of 590,842,140,972 is 845022780.
