HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 898, 616, 35, 478 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 898, 616, 35, 478 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 898, 616, 35, 478 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 898, 616, 35, 478 is 1.
HCF(898, 616, 35, 478) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 898, 616, 35, 478 is 1.
Step 1: Since 898 > 616, we apply the division lemma to 898 and 616, to get
898 = 616 x 1 + 282
Step 2: Since the reminder 616 ≠ 0, we apply division lemma to 282 and 616, to get
616 = 282 x 2 + 52
Step 3: We consider the new divisor 282 and the new remainder 52, and apply the division lemma to get
282 = 52 x 5 + 22
We consider the new divisor 52 and the new remainder 22,and apply the division lemma to get
52 = 22 x 2 + 8
We consider the new divisor 22 and the new remainder 8,and apply the division lemma to get
22 = 8 x 2 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 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 898 and 616 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(22,8) = HCF(52,22) = HCF(282,52) = HCF(616,282) = HCF(898,616) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 35 > 2, we apply the division lemma to 35 and 2, to get
35 = 2 x 17 + 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 35 is 1
Notice that 1 = HCF(2,1) = HCF(35,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 1, we apply the division lemma to 478 and 1, to get
478 = 1 x 478 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 478 is 1
Notice that 1 = HCF(478,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
