HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 769, 450 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 769, 450 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 769, 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 769, 450 is 1.
HCF(769, 450) = 1
HCF of 769, 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 769, 450 is 1.
Highest Common Factor of 769,450 is 1
Step 1: Since 769 > 450, we apply the division lemma to 769 and 450, to get
769 = 450 x 1 + 319
Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 319 and 450, to get
450 = 319 x 1 + 131
Step 3: We consider the new divisor 319 and the new remainder 131, and apply the division lemma to get
319 = 131 x 2 + 57
We consider the new divisor 131 and the new remainder 57,and apply the division lemma to get
131 = 57 x 2 + 17
We consider the new divisor 57 and the new remainder 17,and apply the division lemma to get
57 = 17 x 3 + 6
We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get
17 = 6 x 2 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 769 and 450 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(57,17) = HCF(131,57) = HCF(319,131) = HCF(450,319) = HCF(769,450) .
