HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 253, 687 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 253, 687 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 253, 687 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 253, 687 is 1.
HCF(253, 687) = 1
HCF of 253, 687 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 253, 687 is 1.
Highest Common Factor of 253,687 is 1
Step 1: Since 687 > 253, we apply the division lemma to 687 and 253, to get
687 = 253 x 2 + 181
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 181 and 253, to get
253 = 181 x 1 + 72
Step 3: We consider the new divisor 181 and the new remainder 72, and apply the division lemma to get
181 = 72 x 2 + 37
We consider the new divisor 72 and the new remainder 37,and apply the division lemma to get
72 = 37 x 1 + 35
We consider the new divisor 37 and the new remainder 35,and apply the division lemma to get
37 = 35 x 1 + 2
We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get
35 = 2 x 17 + 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 253 and 687 is 1
Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(37,35) = HCF(72,37) = HCF(181,72) = HCF(253,181) = HCF(687,253) .
