HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 978, 627, 140, 762 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 978, 627, 140, 762 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 978, 627, 140, 762 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 978, 627, 140, 762 is 1.
HCF(978, 627, 140, 762) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 978, 627, 140, 762 is 1.
Step 1: Since 978 > 627, we apply the division lemma to 978 and 627, to get
978 = 627 x 1 + 351
Step 2: Since the reminder 627 ≠ 0, we apply division lemma to 351 and 627, to get
627 = 351 x 1 + 276
Step 3: We consider the new divisor 351 and the new remainder 276, and apply the division lemma to get
351 = 276 x 1 + 75
We consider the new divisor 276 and the new remainder 75,and apply the division lemma to get
276 = 75 x 3 + 51
We consider the new divisor 75 and the new remainder 51,and apply the division lemma to get
75 = 51 x 1 + 24
We consider the new divisor 51 and the new remainder 24,and apply the division lemma to get
51 = 24 x 2 + 3
We consider the new divisor 24 and the new remainder 3,and apply the division lemma to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 978 and 627 is 3
Notice that 3 = HCF(24,3) = HCF(51,24) = HCF(75,51) = HCF(276,75) = HCF(351,276) = HCF(627,351) = HCF(978,627) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 140 > 3, we apply the division lemma to 140 and 3, to get
140 = 3 x 46 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 140 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(140,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 1, we apply the division lemma to 762 and 1, to get
762 = 1 x 762 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 762 is 1
Notice that 1 = HCF(762,1) .
