HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 998, 653, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 998, 653, 651 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, 653, 651 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, 653, 651 is 1.
HCF(998, 653, 651) = 1
HCF of 998, 653, 651 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, 653, 651 is 1.
Highest Common Factor of 998,653,651 is 1
Step 1: Since 998 > 653, we apply the division lemma to 998 and 653, to get
998 = 653 x 1 + 345
Step 2: Since the reminder 653 ≠ 0, we apply division lemma to 345 and 653, to get
653 = 345 x 1 + 308
Step 3: We consider the new divisor 345 and the new remainder 308, and apply the division lemma to get
345 = 308 x 1 + 37
We consider the new divisor 308 and the new remainder 37,and apply the division lemma to get
308 = 37 x 8 + 12
We consider the new divisor 37 and the new remainder 12,and apply the division lemma to get
37 = 12 x 3 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 998 and 653 is 1
Notice that 1 = HCF(12,1) = HCF(37,12) = HCF(308,37) = HCF(345,308) = HCF(653,345) = HCF(998,653) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 1, we apply the division lemma to 651 and 1, to get
651 = 1 x 651 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 651 is 1
Notice that 1 = HCF(651,1) .
