HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 532, 491, 638 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 532, 491, 638 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, 491, 638 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, 491, 638 is 1.
HCF(532, 491, 638) = 1
HCF of 532, 491, 638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 532, 491, 638 is 1.
Highest Common Factor of 532,491,638 is 1
Step 1: Since 532 > 491, we apply the division lemma to 532 and 491, to get
532 = 491 x 1 + 41
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 41 and 491, to get
491 = 41 x 11 + 40
Step 3: We consider the new divisor 41 and the new remainder 40, and apply the division lemma to get
41 = 40 x 1 + 1
We consider the new divisor 40 and the new remainder 1, and apply the division lemma to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 532 and 491 is 1
Notice that 1 = HCF(40,1) = HCF(41,40) = HCF(491,41) = HCF(532,491) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 638 > 1, we apply the division lemma to 638 and 1, to get
638 = 1 x 638 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 638 is 1
Notice that 1 = HCF(638,1) .
