HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 137, 521 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 137, 521 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 137, 521 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 137, 521 is 1.
HCF(137, 521) = 1
HCF of 137, 521 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 137, 521 is 1.
Highest Common Factor of 137,521 is 1
Step 1: Since 521 > 137, we apply the division lemma to 521 and 137, to get
521 = 137 x 3 + 110
Step 2: Since the reminder 137 ≠ 0, we apply division lemma to 110 and 137, to get
137 = 110 x 1 + 27
Step 3: We consider the new divisor 110 and the new remainder 27, and apply the division lemma to get
110 = 27 x 4 + 2
We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get
27 = 2 x 13 + 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 137 and 521 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(110,27) = HCF(137,110) = HCF(521,137) .
