HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 147, 856, 543, 812 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 147, 856, 543, 812 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 147, 856, 543, 812 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 147, 856, 543, 812 is 1.
HCF(147, 856, 543, 812) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 147, 856, 543, 812 is 1.
Step 1: Since 856 > 147, we apply the division lemma to 856 and 147, to get
856 = 147 x 5 + 121
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 121 and 147, to get
147 = 121 x 1 + 26
Step 3: We consider the new divisor 121 and the new remainder 26, and apply the division lemma to get
121 = 26 x 4 + 17
We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get
26 = 17 x 1 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 147 and 856 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(121,26) = HCF(147,121) = HCF(856,147) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 543 > 1, we apply the division lemma to 543 and 1, to get
543 = 1 x 543 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 543 is 1
Notice that 1 = HCF(543,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 812 > 1, we apply the division lemma to 812 and 1, to get
812 = 1 x 812 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 812 is 1
Notice that 1 = HCF(812,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
