HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 910, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 910, 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 910, 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 910, 661 is 1.
HCF(910, 661) = 1
HCF of 910, 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 910, 661 is 1.
Highest Common Factor of 910,661 is 1
Step 1: Since 910 > 661, we apply the division lemma to 910 and 661, to get
910 = 661 x 1 + 249
Step 2: Since the reminder 661 ≠ 0, we apply division lemma to 249 and 661, to get
661 = 249 x 2 + 163
Step 3: We consider the new divisor 249 and the new remainder 163, and apply the division lemma to get
249 = 163 x 1 + 86
We consider the new divisor 163 and the new remainder 86,and apply the division lemma to get
163 = 86 x 1 + 77
We consider the new divisor 86 and the new remainder 77,and apply the division lemma to get
86 = 77 x 1 + 9
We consider the new divisor 77 and the new remainder 9,and apply the division lemma to get
77 = 9 x 8 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 910 and 661 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(77,9) = HCF(86,77) = HCF(163,86) = HCF(249,163) = HCF(661,249) = HCF(910,661) .
