HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 172, 499, 33 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 664, 172, 499, 33 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 664, 172, 499, 33 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 664, 172, 499, 33 is 1.
HCF(664, 172, 499, 33) = 1
HCF of 664, 172, 499, 33 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 664, 172, 499, 33 is 1.
Highest Common Factor of 664,172,499,33 is 1
Step 1: Since 664 > 172, we apply the division lemma to 664 and 172, to get
664 = 172 x 3 + 148
Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 148 and 172, to get
172 = 148 x 1 + 24
Step 3: We consider the new divisor 148 and the new remainder 24, and apply the division lemma to get
148 = 24 x 6 + 4
We consider the new divisor 24 and the new remainder 4, and apply the division lemma to get
24 = 4 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 664 and 172 is 4
Notice that 4 = HCF(24,4) = HCF(148,24) = HCF(172,148) = HCF(664,172) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 499 > 4, we apply the division lemma to 499 and 4, to get
499 = 4 x 124 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 499 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(499,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 33 > 1, we apply the division lemma to 33 and 1, to get
33 = 1 x 33 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 33 is 1
Notice that 1 = HCF(33,1) .
