HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 898, 402 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 484, 898, 402 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 484, 898, 402 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, 898, 402 is 2.
HCF(484, 898, 402) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 484, 898, 402 is 2.
Step 1: Since 898 > 484, we apply the division lemma to 898 and 484, to get
898 = 484 x 1 + 414
Step 2: Since the reminder 484 ≠ 0, we apply division lemma to 414 and 484, to get
484 = 414 x 1 + 70
Step 3: We consider the new divisor 414 and the new remainder 70, and apply the division lemma to get
414 = 70 x 5 + 64
We consider the new divisor 70 and the new remainder 64,and apply the division lemma to get
70 = 64 x 1 + 6
We consider the new divisor 64 and the new remainder 6,and apply the division lemma to get
64 = 6 x 10 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 484 and 898 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(64,6) = HCF(70,64) = HCF(414,70) = HCF(484,414) = HCF(898,484) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 402 > 2, we apply the division lemma to 402 and 2, to get
402 = 2 x 201 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 402 is 2
Notice that 2 = HCF(402,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
