HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 903 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 801, 903 is 3 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 801, 903 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 801, 903 is 3.
HCF(801, 903) = 3
HCF of 801, 903 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 801, 903 is 3.
Highest Common Factor of 801,903 is 3
Step 1: Since 903 > 801, we apply the division lemma to 903 and 801, to get
903 = 801 x 1 + 102
Step 2: Since the reminder 801 ≠ 0, we apply division lemma to 102 and 801, to get
801 = 102 x 7 + 87
Step 3: We consider the new divisor 102 and the new remainder 87, and apply the division lemma to get
102 = 87 x 1 + 15
We consider the new divisor 87 and the new remainder 15,and apply the division lemma to get
87 = 15 x 5 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 801 and 903 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(87,15) = HCF(102,87) = HCF(801,102) = HCF(903,801) .
