HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 22, 15, 86, 208 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 22, 15, 86, 208 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 22, 15, 86, 208 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 22, 15, 86, 208 is 1.
HCF(22, 15, 86, 208) = 1
HCF of 22, 15, 86, 208 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 22, 15, 86, 208 is 1.
Highest Common Factor of 22,15,86,208 is 1
Step 1: Since 22 > 15, we apply the division lemma to 22 and 15, to get
22 = 15 x 1 + 7
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 7 and 15, to get
15 = 7 x 2 + 1
Step 3: We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 22 and 15 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) .
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 208 > 1, we apply the division lemma to 208 and 1, to get
208 = 1 x 208 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 208 is 1
Notice that 1 = HCF(208,1) .
