HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 829, 639, 174, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 829, 639, 174, 54 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 829, 639, 174, 54 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 829, 639, 174, 54 is 1.
HCF(829, 639, 174, 54) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 829, 639, 174, 54 is 1.
Step 1: Since 829 > 639, we apply the division lemma to 829 and 639, to get
829 = 639 x 1 + 190
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 190 and 639, to get
639 = 190 x 3 + 69
Step 3: We consider the new divisor 190 and the new remainder 69, and apply the division lemma to get
190 = 69 x 2 + 52
We consider the new divisor 69 and the new remainder 52,and apply the division lemma to get
69 = 52 x 1 + 17
We consider the new divisor 52 and the new remainder 17,and apply the division lemma to get
52 = 17 x 3 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 829 and 639 is 1
Notice that 1 = HCF(17,1) = HCF(52,17) = HCF(69,52) = HCF(190,69) = HCF(639,190) = HCF(829,639) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 174 > 1, we apply the division lemma to 174 and 1, to get
174 = 1 x 174 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 174 is 1
Notice that 1 = HCF(174,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get
54 = 1 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1
Notice that 1 = HCF(54,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
