HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 158, 903 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 158, 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 158, 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 158, 903 is 1.
HCF(158, 903) = 1
HCF of 158, 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 158, 903 is 1.
Highest Common Factor of 158,903 is 1
Step 1: Since 903 > 158, we apply the division lemma to 903 and 158, to get
903 = 158 x 5 + 113
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 113 and 158, to get
158 = 113 x 1 + 45
Step 3: We consider the new divisor 113 and the new remainder 45, and apply the division lemma to get
113 = 45 x 2 + 23
We consider the new divisor 45 and the new remainder 23,and apply the division lemma to get
45 = 23 x 1 + 22
We consider the new divisor 23 and the new remainder 22,and apply the division lemma to get
23 = 22 x 1 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 158 and 903 is 1
Notice that 1 = HCF(22,1) = HCF(23,22) = HCF(45,23) = HCF(113,45) = HCF(158,113) = HCF(903,158) .
