HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 384, 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 384, 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 384, 661 is 1.
HCF(384, 661) = 1
HCF of 384, 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 384, 661 is 1.
Highest Common Factor of 384,661 is 1
Step 1: Since 661 > 384, we apply the division lemma to 661 and 384, to get
661 = 384 x 1 + 277
Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 277 and 384, to get
384 = 277 x 1 + 107
Step 3: We consider the new divisor 277 and the new remainder 107, and apply the division lemma to get
277 = 107 x 2 + 63
We consider the new divisor 107 and the new remainder 63,and apply the division lemma to get
107 = 63 x 1 + 44
We consider the new divisor 63 and the new remainder 44,and apply the division lemma to get
63 = 44 x 1 + 19
We consider the new divisor 44 and the new remainder 19,and apply the division lemma to get
44 = 19 x 2 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 384 and 661 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(44,19) = HCF(63,44) = HCF(107,63) = HCF(277,107) = HCF(384,277) = HCF(661,384) .
