HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 95, 450, 780 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 95, 450, 780 is 5 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 95, 450, 780 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 95, 450, 780 is 5.
HCF(95, 450, 780) = 5
HCF of 95, 450, 780 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 95, 450, 780 is 5.
Highest Common Factor of 95,450,780 is 5
Step 1: Since 450 > 95, we apply the division lemma to 450 and 95, to get
450 = 95 x 4 + 70
Step 2: Since the reminder 95 ≠ 0, we apply division lemma to 70 and 95, to get
95 = 70 x 1 + 25
Step 3: We consider the new divisor 70 and the new remainder 25, and apply the division lemma to get
70 = 25 x 2 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 95 and 450 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(70,25) = HCF(95,70) = HCF(450,95) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 780 > 5, we apply the division lemma to 780 and 5, to get
780 = 5 x 156 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 780 is 5
Notice that 5 = HCF(780,5) .
