HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 828, 396, 715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 828, 396, 715 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 828, 396, 715 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 828, 396, 715 is 1.
HCF(828, 396, 715) = 1
HCF of 828, 396, 715 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 828, 396, 715 is 1.
Highest Common Factor of 828,396,715 is 1
Step 1: Since 828 > 396, we apply the division lemma to 828 and 396, to get
828 = 396 x 2 + 36
Step 2: Since the reminder 396 ≠ 0, we apply division lemma to 36 and 396, to get
396 = 36 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 36, the HCF of 828 and 396 is 36
Notice that 36 = HCF(396,36) = HCF(828,396) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 715 > 36, we apply the division lemma to 715 and 36, to get
715 = 36 x 19 + 31
Step 2: Since the reminder 36 ≠ 0, we apply division lemma to 31 and 36, to get
36 = 31 x 1 + 5
Step 3: We consider the new divisor 31 and the new remainder 5, and apply the division lemma to get
31 = 5 x 6 + 1
We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 36 and 715 is 1
Notice that 1 = HCF(5,1) = HCF(31,5) = HCF(36,31) = HCF(715,36) .
