HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 808, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 484, 808, 657 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 484, 808, 657 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 484, 808, 657 is 1.
HCF(484, 808, 657) = 1
HCF of 484, 808, 657 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 484, 808, 657 is 1.
Highest Common Factor of 484,808,657 is 1
Step 1: Since 808 > 484, we apply the division lemma to 808 and 484, to get
808 = 484 x 1 + 324
Step 2: Since the reminder 484 ≠ 0, we apply division lemma to 324 and 484, to get
484 = 324 x 1 + 160
Step 3: We consider the new divisor 324 and the new remainder 160, and apply the division lemma to get
324 = 160 x 2 + 4
We consider the new divisor 160 and the new remainder 4, and apply the division lemma to get
160 = 4 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 484 and 808 is 4
Notice that 4 = HCF(160,4) = HCF(324,160) = HCF(484,324) = HCF(808,484) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 657 > 4, we apply the division lemma to 657 and 4, to get
657 = 4 x 164 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 657 is 1
Notice that 1 = HCF(4,1) = HCF(657,4) .
