HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 3899 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 3899 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 655, 3899 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 655, 3899 is 1.
HCF(655, 3899) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 655, 3899 is 1.
Step 1: Since 3899 > 655, we apply the division lemma to 3899 and 655, to get
3899 = 655 x 5 + 624
Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 624 and 655, to get
655 = 624 x 1 + 31
Step 3: We consider the new divisor 624 and the new remainder 31, and apply the division lemma to get
624 = 31 x 20 + 4
We consider the new divisor 31 and the new remainder 4,and apply the division lemma to get
31 = 4 x 7 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 655 and 3899 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(31,4) = HCF(624,31) = HCF(655,624) = HCF(3899,655) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
