HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 85, 306, 486, 910 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 85, 306, 486, 910 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 85, 306, 486, 910 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 85, 306, 486, 910 is 1.
HCF(85, 306, 486, 910) = 1
HCF of 85, 306, 486, 910 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 85, 306, 486, 910 is 1.
Highest Common Factor of 85,306,486,910 is 1
Step 1: Since 306 > 85, we apply the division lemma to 306 and 85, to get
306 = 85 x 3 + 51
Step 2: Since the reminder 85 ≠ 0, we apply division lemma to 51 and 85, to get
85 = 51 x 1 + 34
Step 3: We consider the new divisor 51 and the new remainder 34, and apply the division lemma to get
51 = 34 x 1 + 17
We consider the new divisor 34 and the new remainder 17, and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 85 and 306 is 17
Notice that 17 = HCF(34,17) = HCF(51,34) = HCF(85,51) = HCF(306,85) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 486 > 17, we apply the division lemma to 486 and 17, to get
486 = 17 x 28 + 10
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 10 and 17, to get
17 = 10 x 1 + 7
Step 3: We consider the new divisor 10 and the new remainder 7, and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 17 and 486 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(486,17) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 910 > 1, we apply the division lemma to 910 and 1, to get
910 = 1 x 910 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 910 is 1
Notice that 1 = HCF(910,1) .
