HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 627, 394, 287, 468 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 627, 394, 287, 468 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 627, 394, 287, 468 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 627, 394, 287, 468 is 1.
HCF(627, 394, 287, 468) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 627, 394, 287, 468 is 1.
Step 1: Since 627 > 394, we apply the division lemma to 627 and 394, to get
627 = 394 x 1 + 233
Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 233 and 394, to get
394 = 233 x 1 + 161
Step 3: We consider the new divisor 233 and the new remainder 161, and apply the division lemma to get
233 = 161 x 1 + 72
We consider the new divisor 161 and the new remainder 72,and apply the division lemma to get
161 = 72 x 2 + 17
We consider the new divisor 72 and the new remainder 17,and apply the division lemma to get
72 = 17 x 4 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 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 627 and 394 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(72,17) = HCF(161,72) = HCF(233,161) = HCF(394,233) = HCF(627,394) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 287 > 1, we apply the division lemma to 287 and 1, to get
287 = 1 x 287 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 287 is 1
Notice that 1 = HCF(287,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 468 > 1, we apply the division lemma to 468 and 1, to get
468 = 1 x 468 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 468 is 1
Notice that 1 = HCF(468,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
