HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 361, 444 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 622, 361, 444 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 622, 361, 444 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 622, 361, 444 is 1.
HCF(622, 361, 444) = 1
HCF of 622, 361, 444 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 622, 361, 444 is 1.
Highest Common Factor of 622,361,444 is 1
Step 1: Since 622 > 361, we apply the division lemma to 622 and 361, to get
622 = 361 x 1 + 261
Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 261 and 361, to get
361 = 261 x 1 + 100
Step 3: We consider the new divisor 261 and the new remainder 100, and apply the division lemma to get
261 = 100 x 2 + 61
We consider the new divisor 100 and the new remainder 61,and apply the division lemma to get
100 = 61 x 1 + 39
We consider the new divisor 61 and the new remainder 39,and apply the division lemma to get
61 = 39 x 1 + 22
We consider the new divisor 39 and the new remainder 22,and apply the division lemma to get
39 = 22 x 1 + 17
We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get
22 = 17 x 1 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 622 and 361 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(39,22) = HCF(61,39) = HCF(100,61) = HCF(261,100) = HCF(361,261) = HCF(622,361) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 444 > 1, we apply the division lemma to 444 and 1, to get
444 = 1 x 444 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 444 is 1
Notice that 1 = HCF(444,1) .
