HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 825 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 431, 825 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 431, 825 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 431, 825 is 1.
HCF(431, 825) = 1
HCF of 431, 825 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 431, 825 is 1.
Highest Common Factor of 431,825 is 1
Step 1: Since 825 > 431, we apply the division lemma to 825 and 431, to get
825 = 431 x 1 + 394
Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 394 and 431, to get
431 = 394 x 1 + 37
Step 3: We consider the new divisor 394 and the new remainder 37, and apply the division lemma to get
394 = 37 x 10 + 24
We consider the new divisor 37 and the new remainder 24,and apply the division lemma to get
37 = 24 x 1 + 13
We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get
24 = 13 x 1 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 431 and 825 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(37,24) = HCF(394,37) = HCF(431,394) = HCF(825,431) .
