HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 457, 836, 812 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 457, 836, 812 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 457, 836, 812 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 457, 836, 812 is 1.
HCF(457, 836, 812) = 1
HCF of 457, 836, 812 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 457, 836, 812 is 1.
Highest Common Factor of 457,836,812 is 1
Step 1: Since 836 > 457, we apply the division lemma to 836 and 457, to get
836 = 457 x 1 + 379
Step 2: Since the reminder 457 ≠ 0, we apply division lemma to 379 and 457, to get
457 = 379 x 1 + 78
Step 3: We consider the new divisor 379 and the new remainder 78, and apply the division lemma to get
379 = 78 x 4 + 67
We consider the new divisor 78 and the new remainder 67,and apply the division lemma to get
78 = 67 x 1 + 11
We consider the new divisor 67 and the new remainder 11,and apply the division lemma to get
67 = 11 x 6 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 457 and 836 is 1
Notice that 1 = HCF(11,1) = HCF(67,11) = HCF(78,67) = HCF(379,78) = HCF(457,379) = HCF(836,457) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 812 > 1, we apply the division lemma to 812 and 1, to get
812 = 1 x 812 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 812 is 1
Notice that 1 = HCF(812,1) .
