HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 831, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 424, 831, 12 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 424, 831, 12 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 424, 831, 12 is 1.
HCF(424, 831, 12) = 1
HCF of 424, 831, 12 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 424, 831, 12 is 1.
Highest Common Factor of 424,831,12 is 1
Step 1: Since 831 > 424, we apply the division lemma to 831 and 424, to get
831 = 424 x 1 + 407
Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 407 and 424, to get
424 = 407 x 1 + 17
Step 3: We consider the new divisor 407 and the new remainder 17, and apply the division lemma to get
407 = 17 x 23 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 424 and 831 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(407,17) = HCF(424,407) = HCF(831,424) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1
Notice that 1 = HCF(12,1) .
