HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 718, 973, 868 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 718, 973, 868 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 718, 973, 868 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 718, 973, 868 is 1.
HCF(718, 973, 868) = 1
HCF of 718, 973, 868 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 718, 973, 868 is 1.
Highest Common Factor of 718,973,868 is 1
Step 1: Since 973 > 718, we apply the division lemma to 973 and 718, to get
973 = 718 x 1 + 255
Step 2: Since the reminder 718 ≠ 0, we apply division lemma to 255 and 718, to get
718 = 255 x 2 + 208
Step 3: We consider the new divisor 255 and the new remainder 208, and apply the division lemma to get
255 = 208 x 1 + 47
We consider the new divisor 208 and the new remainder 47,and apply the division lemma to get
208 = 47 x 4 + 20
We consider the new divisor 47 and the new remainder 20,and apply the division lemma to get
47 = 20 x 2 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 718 and 973 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(47,20) = HCF(208,47) = HCF(255,208) = HCF(718,255) = HCF(973,718) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 868 > 1, we apply the division lemma to 868 and 1, to get
868 = 1 x 868 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 868 is 1
Notice that 1 = HCF(868,1) .
