HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 661, 604 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 661, 604 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 661, 604 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 661, 604 is 1.
HCF(661, 604) = 1
HCF of 661, 604 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 661, 604 is 1.
Highest Common Factor of 661,604 is 1
Step 1: Since 661 > 604, we apply the division lemma to 661 and 604, to get
661 = 604 x 1 + 57
Step 2: Since the reminder 604 ≠ 0, we apply division lemma to 57 and 604, to get
604 = 57 x 10 + 34
Step 3: We consider the new divisor 57 and the new remainder 34, and apply the division lemma to get
57 = 34 x 1 + 23
We consider the new divisor 34 and the new remainder 23,and apply the division lemma to get
34 = 23 x 1 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 661 and 604 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(34,23) = HCF(57,34) = HCF(604,57) = HCF(661,604) .
