HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 802, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 994, 802, 997 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 994, 802, 997 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 994, 802, 997 is 1.
HCF(994, 802, 997) = 1
HCF of 994, 802, 997 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 994, 802, 997 is 1.
Highest Common Factor of 994,802,997 is 1
Step 1: Since 994 > 802, we apply the division lemma to 994 and 802, to get
994 = 802 x 1 + 192
Step 2: Since the reminder 802 ≠ 0, we apply division lemma to 192 and 802, to get
802 = 192 x 4 + 34
Step 3: We consider the new divisor 192 and the new remainder 34, and apply the division lemma to get
192 = 34 x 5 + 22
We consider the new divisor 34 and the new remainder 22,and apply the division lemma to get
34 = 22 x 1 + 12
We consider the new divisor 22 and the new remainder 12,and apply the division lemma to get
22 = 12 x 1 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 994 and 802 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(34,22) = HCF(192,34) = HCF(802,192) = HCF(994,802) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 997 > 2, we apply the division lemma to 997 and 2, to get
997 = 2 x 498 + 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 997 is 1
Notice that 1 = HCF(2,1) = HCF(997,2) .
