HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 781, 627 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 471, 781, 627 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 471, 781, 627 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 471, 781, 627 is 1.
HCF(471, 781, 627) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 471, 781, 627 is 1.
Step 1: Since 781 > 471, we apply the division lemma to 781 and 471, to get
781 = 471 x 1 + 310
Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 310 and 471, to get
471 = 310 x 1 + 161
Step 3: We consider the new divisor 310 and the new remainder 161, and apply the division lemma to get
310 = 161 x 1 + 149
We consider the new divisor 161 and the new remainder 149,and apply the division lemma to get
161 = 149 x 1 + 12
We consider the new divisor 149 and the new remainder 12,and apply the division lemma to get
149 = 12 x 12 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 471 and 781 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(149,12) = HCF(161,149) = HCF(310,161) = HCF(471,310) = HCF(781,471) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 627 > 1, we apply the division lemma to 627 and 1, to get
627 = 1 x 627 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 627 is 1
Notice that 1 = HCF(627,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
