HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 626, 64, 164 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 626, 64, 164 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 388, 626, 64, 164 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 388, 626, 64, 164 is 2.
HCF(388, 626, 64, 164) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 626, 64, 164 is 2.
Step 1: Since 626 > 388, we apply the division lemma to 626 and 388, to get
626 = 388 x 1 + 238
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 238 and 388, to get
388 = 238 x 1 + 150
Step 3: We consider the new divisor 238 and the new remainder 150, and apply the division lemma to get
238 = 150 x 1 + 88
We consider the new divisor 150 and the new remainder 88,and apply the division lemma to get
150 = 88 x 1 + 62
We consider the new divisor 88 and the new remainder 62,and apply the division lemma to get
88 = 62 x 1 + 26
We consider the new divisor 62 and the new remainder 26,and apply the division lemma to get
62 = 26 x 2 + 10
We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get
26 = 10 x 2 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 388 and 626 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(62,26) = HCF(88,62) = HCF(150,88) = HCF(238,150) = HCF(388,238) = HCF(626,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 64 > 2, we apply the division lemma to 64 and 2, to get
64 = 2 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 64 is 2
Notice that 2 = HCF(64,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 164 > 2, we apply the division lemma to 164 and 2, to get
164 = 2 x 82 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 164 is 2
Notice that 2 = HCF(164,2) .
