HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 494, 699 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 812, 494, 699 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 812, 494, 699 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 812, 494, 699 is 1.
HCF(812, 494, 699) = 1
HCF of 812, 494, 699 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 812, 494, 699 is 1.
Highest Common Factor of 812,494,699 is 1
Step 1: Since 812 > 494, we apply the division lemma to 812 and 494, to get
812 = 494 x 1 + 318
Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 318 and 494, to get
494 = 318 x 1 + 176
Step 3: We consider the new divisor 318 and the new remainder 176, and apply the division lemma to get
318 = 176 x 1 + 142
We consider the new divisor 176 and the new remainder 142,and apply the division lemma to get
176 = 142 x 1 + 34
We consider the new divisor 142 and the new remainder 34,and apply the division lemma to get
142 = 34 x 4 + 6
We consider the new divisor 34 and the new remainder 6,and apply the division lemma to get
34 = 6 x 5 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 812 and 494 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(34,6) = HCF(142,34) = HCF(176,142) = HCF(318,176) = HCF(494,318) = HCF(812,494) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 699 > 2, we apply the division lemma to 699 and 2, to get
699 = 2 x 349 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 699 is 1
Notice that 1 = HCF(2,1) = HCF(699,2) .
