HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 773 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 773 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, 773 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, 773 is 1.
HCF(998, 773) = 1
HCF of 998, 773 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, 773 is 1.
Highest Common Factor of 998,773 is 1
Step 1: Since 998 > 773, we apply the division lemma to 998 and 773, to get
998 = 773 x 1 + 225
Step 2: Since the reminder 773 ≠ 0, we apply division lemma to 225 and 773, to get
773 = 225 x 3 + 98
Step 3: We consider the new divisor 225 and the new remainder 98, and apply the division lemma to get
225 = 98 x 2 + 29
We consider the new divisor 98 and the new remainder 29,and apply the division lemma to get
98 = 29 x 3 + 11
We consider the new divisor 29 and the new remainder 11,and apply the division lemma to get
29 = 11 x 2 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 998 and 773 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(29,11) = HCF(98,29) = HCF(225,98) = HCF(773,225) = HCF(998,773) .
