HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 90, 80, 86 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 90, 80, 86 is 2 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 90, 80, 86 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 90, 80, 86 is 2.
HCF(90, 80, 86) = 2
HCF of 90, 80, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 90, 80, 86 is 2.
Highest Common Factor of 90,80,86 is 2
Step 1: Since 90 > 80, we apply the division lemma to 90 and 80, to get
90 = 80 x 1 + 10
Step 2: Since the reminder 80 ≠ 0, we apply division lemma to 10 and 80, to get
80 = 10 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 90 and 80 is 10
Notice that 10 = HCF(80,10) = HCF(90,80) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 10, we apply the division lemma to 86 and 10, to get
86 = 10 x 8 + 6
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get
10 = 6 x 1 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 86 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(86,10) .
