HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 279, 242, 422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 279, 242, 422 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 279, 242, 422 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 279, 242, 422 is 1.
HCF(279, 242, 422) = 1
HCF of 279, 242, 422 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 279, 242, 422 is 1.
Highest Common Factor of 279,242,422 is 1
Step 1: Since 279 > 242, we apply the division lemma to 279 and 242, to get
279 = 242 x 1 + 37
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 37 and 242, to get
242 = 37 x 6 + 20
Step 3: We consider the new divisor 37 and the new remainder 20, and apply the division lemma to get
37 = 20 x 1 + 17
We consider the new divisor 20 and the new remainder 17,and apply the division lemma to get
20 = 17 x 1 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 279 and 242 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(37,20) = HCF(242,37) = HCF(279,242) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 422 > 1, we apply the division lemma to 422 and 1, to get
422 = 1 x 422 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 422 is 1
Notice that 1 = HCF(422,1) .
