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

2 x 2 x 2 x 2 x 2 x 7 x 23 x 419 x 3 x 1 x 1 = 6476064

Therefore, the lowest common multiple of 419,672,736,644 is 6476064.

LCM Formula to Find Lowest Common Multiple of 419,672,736,644

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.

419 x 672 x 736 x 644 = 133458726912

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.

419 : 1, 419

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,672,736,644, is 1.

Now, the common factors can be found like this.

419:419

672:2x 2x 2x 2x 2x 3x 7

736:2x 2x 2x 2x 2x 23

644:2x 2x 7x 23

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 2x 2x 2x 2x 7x 23 = 20608

Therefore, the value for common factors is 20608.

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 = 133458726912/(1x20608)

LCM = 133458726912/20608

LCM = 6476064

Thus, we can understand that the LCM of 419,672,736,644 is 6476064.
