HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 423, 556, 436 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 423, 556, 436 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 423, 556, 436 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 423, 556, 436 is 1.

HCF(423, 556, 436) = 1

Highest common factor (HCF) of 423, 556, 436 is 1.

Highest Common Factor of 423,556,436 using Euclid's algorithm

Highest Common Factor of 423,556,436 is 1

Step 1: Since 556 > 423, we apply the division lemma to 556 and 423, to get

556 = 423 x 1 + 133

Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 133 and 423, to get

423 = 133 x 3 + 24

Step 3: We consider the new divisor 133 and the new remainder 24, and apply the division lemma to get

133 = 24 x 5 + 13

We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get

24 = 13 x 1 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 423 and 556 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(133,24) = HCF(423,133) = HCF(556,423) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 436 > 1, we apply the division lemma to 436 and 1, to get

436 = 1 x 436 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 436 is 1

Notice that 1 = HCF(436,1) .
