HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 979, 221, 903 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 979, 221, 903 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 979, 221, 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 979, 221, 903 is 1.
HCF(979, 221, 903) = 1
HCF of 979, 221, 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 979, 221, 903 is 1.
Highest Common Factor of 979,221,903 is 1
Step 1: Since 979 > 221, we apply the division lemma to 979 and 221, to get
979 = 221 x 4 + 95
Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 95 and 221, to get
221 = 95 x 2 + 31
Step 3: We consider the new divisor 95 and the new remainder 31, and apply the division lemma to get
95 = 31 x 3 + 2
We consider the new divisor 31 and the new remainder 2,and apply the division lemma to get
31 = 2 x 15 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 979 and 221 is 1
Notice that 1 = HCF(2,1) = HCF(31,2) = HCF(95,31) = HCF(221,95) = HCF(979,221) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 903 > 1, we apply the division lemma to 903 and 1, to get
903 = 1 x 903 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 903 is 1
Notice that 1 = HCF(903,1) .
