HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 33, 168, 361, 689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 33, 168, 361, 689 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 33, 168, 361, 689 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 33, 168, 361, 689 is 1.
HCF(33, 168, 361, 689) = 1
HCF of 33, 168, 361, 689 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 33, 168, 361, 689 is 1.
Highest Common Factor of 33,168,361,689 is 1
Step 1: Since 168 > 33, we apply the division lemma to 168 and 33, to get
168 = 33 x 5 + 3
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 3 and 33, to get
33 = 3 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 33 and 168 is 3
Notice that 3 = HCF(33,3) = HCF(168,33) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 361 > 3, we apply the division lemma to 361 and 3, to get
361 = 3 x 120 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 361 is 1
Notice that 1 = HCF(3,1) = HCF(361,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 689 > 1, we apply the division lemma to 689 and 1, to get
689 = 1 x 689 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 689 is 1
Notice that 1 = HCF(689,1) .
