HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 84788 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 84788 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 621, 84788 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 621, 84788 is 1.
HCF(621, 84788) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 84788 is 1.
Step 1: Since 84788 > 621, we apply the division lemma to 84788 and 621, to get
84788 = 621 x 136 + 332
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 332 and 621, to get
621 = 332 x 1 + 289
Step 3: We consider the new divisor 332 and the new remainder 289, and apply the division lemma to get
332 = 289 x 1 + 43
We consider the new divisor 289 and the new remainder 43,and apply the division lemma to get
289 = 43 x 6 + 31
We consider the new divisor 43 and the new remainder 31,and apply the division lemma to get
43 = 31 x 1 + 12
We consider the new divisor 31 and the new remainder 12,and apply the division lemma to get
31 = 12 x 2 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 621 and 84788 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(31,12) = HCF(43,31) = HCF(289,43) = HCF(332,289) = HCF(621,332) = HCF(84788,621) .
Here are some samples of HCF using Euclid's Algorithm calculations.
