Given numbers are 661,526,908,840,778

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

The LCM of 661,526,908,840,778 is 12894721080360.

Find LCM of 661,526,908,840,778 with Prime Factorization

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

2 x 2 x 661 x 263 x 227 x 210 x 389 = 12894721080360

Therefore, the lowest common multiple of 661,526,908,840,778 is 12894721080360.

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.

661 x 526 x 908 x 840 x 778 = 206315537285760

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.

661 : 1, 661

526 : 1, 2, 263, 526

908 : 1, 2, 4, 227, 454, 908

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,526,908,840,778, is 1.

Now, the common factors can be found like this.

661:661

526:2x 263

908:2x 2x 227

840:2x 2x 2x 3x 5x 7

778:2x 389

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 2 = 16

Therefore, the value for common factors is 16.

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 = 206315537285760/(1x16)

LCM = 206315537285760/16

LCM = 12894721080360

Thus, we can understand that the LCM of 661,526,908,840,778 is 12894721080360.
