HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 993, 442 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 993, 442 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 868, 993, 442 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 868, 993, 442 is 1.
HCF(868, 993, 442) = 1
HCF of 868, 993, 442 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 993, 442 is 1.
Highest Common Factor of 868,993,442 is 1
Step 1: Since 993 > 868, we apply the division lemma to 993 and 868, to get
993 = 868 x 1 + 125
Step 2: Since the reminder 868 ≠ 0, we apply division lemma to 125 and 868, to get
868 = 125 x 6 + 118
Step 3: We consider the new divisor 125 and the new remainder 118, and apply the division lemma to get
125 = 118 x 1 + 7
We consider the new divisor 118 and the new remainder 7,and apply the division lemma to get
118 = 7 x 16 + 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 868 and 993 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(118,7) = HCF(125,118) = HCF(868,125) = HCF(993,868) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 442 > 1, we apply the division lemma to 442 and 1, to get
442 = 1 x 442 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 442 is 1
Notice that 1 = HCF(442,1) .
