HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 677, 596 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 438, 677, 596 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 438, 677, 596 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 438, 677, 596 is 1.

HCF(438, 677, 596) = 1

HCF of 438, 677, 596 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 438, 677, 596 is 1.

Highest Common Factor of 438,677,596 using Euclid's algorithm

Highest Common Factor of 438,677,596 is 1

Step 1: Since 677 > 438, we apply the division lemma to 677 and 438, to get

677 = 438 x 1 + 239

Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 239 and 438, to get

438 = 239 x 1 + 199

Step 3: We consider the new divisor 239 and the new remainder 199, and apply the division lemma to get

239 = 199 x 1 + 40

We consider the new divisor 199 and the new remainder 40,and apply the division lemma to get

199 = 40 x 4 + 39

We consider the new divisor 40 and the new remainder 39,and apply the division lemma to get

40 = 39 x 1 + 1

We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get

39 = 1 x 39 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 438 and 677 is 1

Notice that 1 = HCF(39,1) = HCF(40,39) = HCF(199,40) = HCF(239,199) = HCF(438,239) = HCF(677,438) .

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

Step 1: Since 596 > 1, we apply the division lemma to 596 and 1, to get

596 = 1 x 596 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 596 is 1

Notice that 1 = HCF(596,1) .
