HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 118, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 118, 253 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 118, 253 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 118, 253 is 1.
HCF(118, 253) = 1
HCF of 118, 253 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 118, 253 is 1.
Highest Common Factor of 118,253 is 1
Step 1: Since 253 > 118, we apply the division lemma to 253 and 118, to get
253 = 118 x 2 + 17
Step 2: Since the reminder 118 ≠ 0, we apply division lemma to 17 and 118, to get
118 = 17 x 6 + 16
Step 3: We consider the new divisor 17 and the new remainder 16, and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1, and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 118 and 253 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(118,17) = HCF(253,118) .
