HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 815, 824 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 815, 824 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 427, 815, 824 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 427, 815, 824 is 1.
HCF(427, 815, 824) = 1
HCF of 427, 815, 824 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 815, 824 is 1.
Highest Common Factor of 427,815,824 is 1
Step 1: Since 815 > 427, we apply the division lemma to 815 and 427, to get
815 = 427 x 1 + 388
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 388 and 427, to get
427 = 388 x 1 + 39
Step 3: We consider the new divisor 388 and the new remainder 39, and apply the division lemma to get
388 = 39 x 9 + 37
We consider the new divisor 39 and the new remainder 37,and apply the division lemma to get
39 = 37 x 1 + 2
We consider the new divisor 37 and the new remainder 2,and apply the division lemma to get
37 = 2 x 18 + 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 427 and 815 is 1
Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(39,37) = HCF(388,39) = HCF(427,388) = HCF(815,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 824 > 1, we apply the division lemma to 824 and 1, to get
824 = 1 x 824 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 824 is 1
Notice that 1 = HCF(824,1) .
