HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 290, 36, 164 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 656, 290, 36, 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 656, 290, 36, 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 656, 290, 36, 164 is 2.
HCF(656, 290, 36, 164) = 2
HCF of 656, 290, 36, 164 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 656, 290, 36, 164 is 2.
Highest Common Factor of 656,290,36,164 is 2
Step 1: Since 656 > 290, we apply the division lemma to 656 and 290, to get
656 = 290 x 2 + 76
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 76 and 290, to get
290 = 76 x 3 + 62
Step 3: We consider the new divisor 76 and the new remainder 62, and apply the division lemma to get
76 = 62 x 1 + 14
We consider the new divisor 62 and the new remainder 14,and apply the division lemma to get
62 = 14 x 4 + 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 656 and 290 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(62,14) = HCF(76,62) = HCF(290,76) = HCF(656,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 36 > 2, we apply the division lemma to 36 and 2, to get
36 = 2 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 36 is 2
Notice that 2 = HCF(36,2) .
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) .
