Calculate the LCM of 946,511,496,947,642

Given numbers are 946,511,496,947,642

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 946,511,496,947,642 is 36443386651056.

Find LCM of 946,511,496,947,642 with Prime Factorization


2 946, 511, 496, 947, 642
473, 511, 248, 947, 321

Multiply the prime numbers at the bottom and the left side.

2 x 473 x 511 x 248 x 947 x 321 = 36443386651056

Therefore, the lowest common multiple of 946,511,496,947,642 is 36443386651056.

LCM Formula to Find Lowest Common Multiple of 946,511,496,947,642

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.

946 x 511 x 496 x 947 x 642 = 145773546604224

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

511 : 1, 7, 73, 511

496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496

947 : 1, 947

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,511,496,947,642, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

511:7x 73

496:2x 2x 2x 2x 31

947:947

642:2x 3x 107

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 145773546604224/(1x4)

LCM = 145773546604224/4

LCM = 36443386651056

Thus, we can understand that the LCM of 946,511,496,947,642 is 36443386651056.
