HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 608 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 608 is 2 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, 608 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, 608 is 2.
HCF(998, 608) = 2
HCF of 998, 608 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, 608 is 2.
Highest Common Factor of 998,608 is 2
Step 1: Since 998 > 608, we apply the division lemma to 998 and 608, to get
998 = 608 x 1 + 390
Step 2: Since the reminder 608 ≠ 0, we apply division lemma to 390 and 608, to get
608 = 390 x 1 + 218
Step 3: We consider the new divisor 390 and the new remainder 218, and apply the division lemma to get
390 = 218 x 1 + 172
We consider the new divisor 218 and the new remainder 172,and apply the division lemma to get
218 = 172 x 1 + 46
We consider the new divisor 172 and the new remainder 46,and apply the division lemma to get
172 = 46 x 3 + 34
We consider the new divisor 46 and the new remainder 34,and apply the division lemma to get
46 = 34 x 1 + 12
We consider the new divisor 34 and the new remainder 12,and apply the division lemma to get
34 = 12 x 2 + 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 998 and 608 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(34,12) = HCF(46,34) = HCF(172,46) = HCF(218,172) = HCF(390,218) = HCF(608,390) = HCF(998,608) .
