HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 233, 522, 179 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 233, 522, 179 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 647, 233, 522, 179 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 647, 233, 522, 179 is 1.
HCF(647, 233, 522, 179) = 1
HCF of 647, 233, 522, 179 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 647, 233, 522, 179 is 1.
Highest Common Factor of 647,233,522,179 is 1
Step 1: Since 647 > 233, we apply the division lemma to 647 and 233, to get
647 = 233 x 2 + 181
Step 2: Since the reminder 233 ≠ 0, we apply division lemma to 181 and 233, to get
233 = 181 x 1 + 52
Step 3: We consider the new divisor 181 and the new remainder 52, and apply the division lemma to get
181 = 52 x 3 + 25
We consider the new divisor 52 and the new remainder 25,and apply the division lemma to get
52 = 25 x 2 + 2
We consider the new divisor 25 and the new remainder 2,and apply the division lemma to get
25 = 2 x 12 + 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 647 and 233 is 1
Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(52,25) = HCF(181,52) = HCF(233,181) = HCF(647,233) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 522 > 1, we apply the division lemma to 522 and 1, to get
522 = 1 x 522 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 522 is 1
Notice that 1 = HCF(522,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 179 > 1, we apply the division lemma to 179 and 1, to get
179 = 1 x 179 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 179 is 1
Notice that 1 = HCF(179,1) .
