HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 312, 739, 422 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 312, 739, 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 312, 739, 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 312, 739, 422 is 1.
HCF(312, 739, 422) = 1
HCF of 312, 739, 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 312, 739, 422 is 1.
Highest Common Factor of 312,739,422 is 1
Step 1: Since 739 > 312, we apply the division lemma to 739 and 312, to get
739 = 312 x 2 + 115
Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 115 and 312, to get
312 = 115 x 2 + 82
Step 3: We consider the new divisor 115 and the new remainder 82, and apply the division lemma to get
115 = 82 x 1 + 33
We consider the new divisor 82 and the new remainder 33,and apply the division lemma to get
82 = 33 x 2 + 16
We consider the new divisor 33 and the new remainder 16,and apply the division lemma to get
33 = 16 x 2 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 312 and 739 is 1
Notice that 1 = HCF(16,1) = HCF(33,16) = HCF(82,33) = HCF(115,82) = HCF(312,115) = HCF(739,312) .
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) .
