HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 694, 220, 353 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 484, 694, 220, 353 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, 694, 220, 353 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, 694, 220, 353 is 1.
HCF(484, 694, 220, 353) = 1
HCF of 484, 694, 220, 353 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, 694, 220, 353 is 1.
Highest Common Factor of 484,694,220,353 is 1
Step 1: Since 694 > 484, we apply the division lemma to 694 and 484, to get
694 = 484 x 1 + 210
Step 2: Since the reminder 484 ≠ 0, we apply division lemma to 210 and 484, to get
484 = 210 x 2 + 64
Step 3: We consider the new divisor 210 and the new remainder 64, and apply the division lemma to get
210 = 64 x 3 + 18
We consider the new divisor 64 and the new remainder 18,and apply the division lemma to get
64 = 18 x 3 + 10
We consider the new divisor 18 and the new remainder 10,and apply the division lemma to get
18 = 10 x 1 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 484 and 694 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(64,18) = HCF(210,64) = HCF(484,210) = HCF(694,484) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 220 > 2, we apply the division lemma to 220 and 2, to get
220 = 2 x 110 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 220 is 2
Notice that 2 = HCF(220,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 353 > 2, we apply the division lemma to 353 and 2, to get
353 = 2 x 176 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 353 is 1
Notice that 1 = HCF(2,1) = HCF(353,2) .
