HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 435, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 435, 661 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 435, 661 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 435, 661 is 1.
HCF(435, 661) = 1
HCF of 435, 661 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 435, 661 is 1.
Highest Common Factor of 435,661 is 1
Step 1: Since 661 > 435, we apply the division lemma to 661 and 435, to get
661 = 435 x 1 + 226
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 226 and 435, to get
435 = 226 x 1 + 209
Step 3: We consider the new divisor 226 and the new remainder 209, and apply the division lemma to get
226 = 209 x 1 + 17
We consider the new divisor 209 and the new remainder 17,and apply the division lemma to get
209 = 17 x 12 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 435 and 661 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(209,17) = HCF(226,209) = HCF(435,226) = HCF(661,435) .
