HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 33, 170, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 689, 33, 170, 279 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 689, 33, 170, 279 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 689, 33, 170, 279 is 1.
HCF(689, 33, 170, 279) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 689, 33, 170, 279 is 1.
Step 1: Since 689 > 33, we apply the division lemma to 689 and 33, to get
689 = 33 x 20 + 29
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 29 and 33, to get
33 = 29 x 1 + 4
Step 3: We consider the new divisor 29 and the new remainder 4, and apply the division lemma to get
29 = 4 x 7 + 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 689 and 33 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(33,29) = HCF(689,33) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 170 > 1, we apply the division lemma to 170 and 1, to get
170 = 1 x 170 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 170 is 1
Notice that 1 = HCF(170,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 279 > 1, we apply the division lemma to 279 and 1, to get
279 = 1 x 279 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 279 is 1
Notice that 1 = HCF(279,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
