HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 8430 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 8430 is 5 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 625, 8430 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 625, 8430 is 5.
HCF(625, 8430) = 5
HCF of 625, 8430 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 625, 8430 is 5.
Highest Common Factor of 625,8430 is 5
Step 1: Since 8430 > 625, we apply the division lemma to 8430 and 625, to get
8430 = 625 x 13 + 305
Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 305 and 625, to get
625 = 305 x 2 + 15
Step 3: We consider the new divisor 305 and the new remainder 15, and apply the division lemma to get
305 = 15 x 20 + 5
We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 625 and 8430 is 5
Notice that 5 = HCF(15,5) = HCF(305,15) = HCF(625,305) = HCF(8430,625) .
