HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 194, 785, 22 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 216, 194, 785, 22 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 216, 194, 785, 22 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 216, 194, 785, 22 is 1.
HCF(216, 194, 785, 22) = 1
HCF of 216, 194, 785, 22 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 216, 194, 785, 22 is 1.
Highest Common Factor of 216,194,785,22 is 1
Step 1: Since 216 > 194, we apply the division lemma to 216 and 194, to get
216 = 194 x 1 + 22
Step 2: Since the reminder 194 ≠ 0, we apply division lemma to 22 and 194, to get
194 = 22 x 8 + 18
Step 3: We consider the new divisor 22 and the new remainder 18, and apply the division lemma to get
22 = 18 x 1 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 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 216 and 194 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(194,22) = HCF(216,194) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 785 > 2, we apply the division lemma to 785 and 2, to get
785 = 2 x 392 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 785 is 1
Notice that 1 = HCF(2,1) = HCF(785,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1
Notice that 1 = HCF(22,1) .
