HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 513, 357 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 513, 357 is 3 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 513, 357 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 513, 357 is 3.
HCF(513, 357) = 3
HCF of 513, 357 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 513, 357 is 3.
Highest Common Factor of 513,357 is 3
Step 1: Since 513 > 357, we apply the division lemma to 513 and 357, to get
513 = 357 x 1 + 156
Step 2: Since the reminder 357 ≠ 0, we apply division lemma to 156 and 357, to get
357 = 156 x 2 + 45
Step 3: We consider the new divisor 156 and the new remainder 45, and apply the division lemma to get
156 = 45 x 3 + 21
We consider the new divisor 45 and the new remainder 21,and apply the division lemma to get
45 = 21 x 2 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 513 and 357 is 3
Notice that 3 = HCF(21,3) = HCF(45,21) = HCF(156,45) = HCF(357,156) = HCF(513,357) .
