HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 532, 434, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 532, 434, 639 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 532, 434, 639 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 532, 434, 639 is 1.

HCF(532, 434, 639) = 1

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

HCF of:

Highest common factor (HCF) of 532, 434, 639 is 1.

Highest Common Factor of 532,434,639 using Euclid's algorithm

Highest Common Factor of 532,434,639 is 1

Step 1: Since 532 > 434, we apply the division lemma to 532 and 434, to get

532 = 434 x 1 + 98

Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 98 and 434, to get

434 = 98 x 4 + 42

Step 3: We consider the new divisor 98 and the new remainder 42, and apply the division lemma to get

98 = 42 x 2 + 14

We consider the new divisor 42 and the new remainder 14, and apply the division lemma to get

42 = 14 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 532 and 434 is 14

Notice that 14 = HCF(42,14) = HCF(98,42) = HCF(434,98) = HCF(532,434) .

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

Step 1: Since 639 > 14, we apply the division lemma to 639 and 14, to get

639 = 14 x 45 + 9

Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 9 and 14, to get

14 = 9 x 1 + 5

Step 3: We consider the new divisor 9 and the new remainder 5, and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 639 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(639,14) .
