HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 132, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 132, 65 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 998, 132, 65 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 998, 132, 65 is 1.
HCF(998, 132, 65) = 1
HCF of 998, 132, 65 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 998, 132, 65 is 1.
Highest Common Factor of 998,132,65 is 1
Step 1: Since 998 > 132, we apply the division lemma to 998 and 132, to get
998 = 132 x 7 + 74
Step 2: Since the reminder 132 ≠ 0, we apply division lemma to 74 and 132, to get
132 = 74 x 1 + 58
Step 3: We consider the new divisor 74 and the new remainder 58, and apply the division lemma to get
74 = 58 x 1 + 16
We consider the new divisor 58 and the new remainder 16,and apply the division lemma to get
58 = 16 x 3 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 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 998 and 132 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(58,16) = HCF(74,58) = HCF(132,74) = HCF(998,132) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 2, we apply the division lemma to 65 and 2, to get
65 = 2 x 32 + 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 65 is 1
Notice that 1 = HCF(2,1) = HCF(65,2) .
