HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 772, 563, 86, 151 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 772, 563, 86, 151 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 772, 563, 86, 151 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 772, 563, 86, 151 is 1.
HCF(772, 563, 86, 151) = 1
HCF of 772, 563, 86, 151 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 772, 563, 86, 151 is 1.
Highest Common Factor of 772,563,86,151 is 1
Step 1: Since 772 > 563, we apply the division lemma to 772 and 563, to get
772 = 563 x 1 + 209
Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 209 and 563, to get
563 = 209 x 2 + 145
Step 3: We consider the new divisor 209 and the new remainder 145, and apply the division lemma to get
209 = 145 x 1 + 64
We consider the new divisor 145 and the new remainder 64,and apply the division lemma to get
145 = 64 x 2 + 17
We consider the new divisor 64 and the new remainder 17,and apply the division lemma to get
64 = 17 x 3 + 13
We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get
17 = 13 x 1 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 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 772 and 563 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(64,17) = HCF(145,64) = HCF(209,145) = HCF(563,209) = HCF(772,563) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get
86 = 1 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1
Notice that 1 = HCF(86,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 151 > 1, we apply the division lemma to 151 and 1, to get
151 = 1 x 151 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 151 is 1
Notice that 1 = HCF(151,1) .
