Given numbers are 780,602,907,126,945

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

The LCM of 780,602,907,126,945 is 1916509140.

Find LCM of 780,602,907,126,945 with Prime Factorization

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

2 x 3 x 3 x 5 x 7 x 26 x 43 x 907 x 1 x 3 = 1916509140

Therefore, the lowest common multiple of 780,602,907,126,945 is 1916509140.

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.

780 x 602 x 907 x 126 x 945 = 50710831844400

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

602 : 1, 2, 7, 14, 43, 86, 301, 602

907 : 1, 907

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,602,907,126,945, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

602:2x 7x 43

907:907

126:2x 3x 3x 7

945:3x 3x 3x 5x 7

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 3x 3x 3x 5x 7x 7 = 26460

Therefore, the value for common factors is 26460.

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 = 50710831844400/(1x26460)

LCM = 50710831844400/26460

LCM = 1916509140

Thus, we can understand that the LCM of 780,602,907,126,945 is 1916509140.
