HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 533, 821, 94 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 857, 533, 821, 94 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 857, 533, 821, 94 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 857, 533, 821, 94 is 1.
HCF(857, 533, 821, 94) = 1
HCF of 857, 533, 821, 94 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 857, 533, 821, 94 is 1.
Highest Common Factor of 857,533,821,94 is 1
Step 1: Since 857 > 533, we apply the division lemma to 857 and 533, to get
857 = 533 x 1 + 324
Step 2: Since the reminder 533 ≠ 0, we apply division lemma to 324 and 533, to get
533 = 324 x 1 + 209
Step 3: We consider the new divisor 324 and the new remainder 209, and apply the division lemma to get
324 = 209 x 1 + 115
We consider the new divisor 209 and the new remainder 115,and apply the division lemma to get
209 = 115 x 1 + 94
We consider the new divisor 115 and the new remainder 94,and apply the division lemma to get
115 = 94 x 1 + 21
We consider the new divisor 94 and the new remainder 21,and apply the division lemma to get
94 = 21 x 4 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 533 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(94,21) = HCF(115,94) = HCF(209,115) = HCF(324,209) = HCF(533,324) = HCF(857,533) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 821 > 1, we apply the division lemma to 821 and 1, to get
821 = 1 x 821 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 821 is 1
Notice that 1 = HCF(821,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 94 > 1, we apply the division lemma to 94 and 1, to get
94 = 1 x 94 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 94 is 1
Notice that 1 = HCF(94,1) .
