Given numbers are 644,535,943,552,379
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,535,943,552,379 is 32122842360.
Find LCM of 644,535,943,552,379 with Prime Factorization
| 2 | 644, 535, 943, 552, 379 |
| 2 | 322, 535, 943, 276, 379 |
| 23 | 161, 535, 943, 138, 379 |
| 7, 535, 41, 6, 379 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 7 x 535 x 41 x 6 x 379 = 32122842360
Therefore, the lowest common multiple of 644,535,943,552,379 is 32122842360.
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.
644 x 535 x 943 x 552 x 379 = 67971934433760
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
535 : 1, 5, 107, 535
943 : 1, 23, 41, 943
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
379 : 1, 379
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,535,943,552,379, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
535:5x 107
943:23x 41
552:2x 2x 2x 3x 23
379:379
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 23x 23 = 2116
Therefore, the value for common factors is 2116.
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 = 67971934433760/(1x2116)
LCM = 67971934433760/2116
LCM = 32122842360
Thus, we can understand that the LCM of 644,535,943,552,379 is 32122842360.
