HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 956, 698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 956, 698 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 813, 956, 698 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 813, 956, 698 is 1.
HCF(813, 956, 698) = 1
HCF of 813, 956, 698 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 813, 956, 698 is 1.
Highest Common Factor of 813,956,698 is 1
Step 1: Since 956 > 813, we apply the division lemma to 956 and 813, to get
956 = 813 x 1 + 143
Step 2: Since the reminder 813 ≠ 0, we apply division lemma to 143 and 813, to get
813 = 143 x 5 + 98
Step 3: We consider the new divisor 143 and the new remainder 98, and apply the division lemma to get
143 = 98 x 1 + 45
We consider the new divisor 98 and the new remainder 45,and apply the division lemma to get
98 = 45 x 2 + 8
We consider the new divisor 45 and the new remainder 8,and apply the division lemma to get
45 = 8 x 5 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 813 and 956 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(45,8) = HCF(98,45) = HCF(143,98) = HCF(813,143) = HCF(956,813) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 698 > 1, we apply the division lemma to 698 and 1, to get
698 = 1 x 698 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 698 is 1
Notice that 1 = HCF(698,1) .
