HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 704, 622, 168 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 704, 622, 168 is 2 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 704, 622, 168 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 704, 622, 168 is 2.
HCF(704, 622, 168) = 2
HCF of 704, 622, 168 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 704, 622, 168 is 2.
Highest Common Factor of 704,622,168 is 2
Step 1: Since 704 > 622, we apply the division lemma to 704 and 622, to get
704 = 622 x 1 + 82
Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 82 and 622, to get
622 = 82 x 7 + 48
Step 3: We consider the new divisor 82 and the new remainder 48, and apply the division lemma to get
82 = 48 x 1 + 34
We consider the new divisor 48 and the new remainder 34,and apply the division lemma to get
48 = 34 x 1 + 14
We consider the new divisor 34 and the new remainder 14,and apply the division lemma to get
34 = 14 x 2 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 704 and 622 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(34,14) = HCF(48,34) = HCF(82,48) = HCF(622,82) = HCF(704,622) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 168 > 2, we apply the division lemma to 168 and 2, to get
168 = 2 x 84 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 168 is 2
Notice that 2 = HCF(168,2) .
