HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 968, 450 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 968, 450 is 2 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 968, 450 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 968, 450 is 2.
HCF(968, 450) = 2
HCF of 968, 450 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 968, 450 is 2.
Highest Common Factor of 968,450 is 2
Step 1: Since 968 > 450, we apply the division lemma to 968 and 450, to get
968 = 450 x 2 + 68
Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 68 and 450, to get
450 = 68 x 6 + 42
Step 3: We consider the new divisor 68 and the new remainder 42, and apply the division lemma to get
68 = 42 x 1 + 26
We consider the new divisor 42 and the new remainder 26,and apply the division lemma to get
42 = 26 x 1 + 16
We consider the new divisor 26 and the new remainder 16,and apply the division lemma to get
26 = 16 x 1 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 968 and 450 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(26,16) = HCF(42,26) = HCF(68,42) = HCF(450,68) = HCF(968,450) .
