HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 679, 322 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 679, 322 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 165, 679, 322 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 165, 679, 322 is 1.
HCF(165, 679, 322) = 1
HCF of 165, 679, 322 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 679, 322 is 1.
Highest Common Factor of 165,679,322 is 1
Step 1: Since 679 > 165, we apply the division lemma to 679 and 165, to get
679 = 165 x 4 + 19
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 19 and 165, to get
165 = 19 x 8 + 13
Step 3: We consider the new divisor 19 and the new remainder 13, and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 165 and 679 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(165,19) = HCF(679,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 322 > 1, we apply the division lemma to 322 and 1, to get
322 = 1 x 322 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 322 is 1
Notice that 1 = HCF(322,1) .
