HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 851, 742, 797, 254 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 851, 742, 797, 254 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 851, 742, 797, 254 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 851, 742, 797, 254 is 1.
HCF(851, 742, 797, 254) = 1
HCF of 851, 742, 797, 254 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 851, 742, 797, 254 is 1.
Highest Common Factor of 851,742,797,254 is 1
Step 1: Since 851 > 742, we apply the division lemma to 851 and 742, to get
851 = 742 x 1 + 109
Step 2: Since the reminder 742 ≠ 0, we apply division lemma to 109 and 742, to get
742 = 109 x 6 + 88
Step 3: We consider the new divisor 109 and the new remainder 88, and apply the division lemma to get
109 = 88 x 1 + 21
We consider the new divisor 88 and the new remainder 21,and apply the division lemma to get
88 = 21 x 4 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 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 851 and 742 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(88,21) = HCF(109,88) = HCF(742,109) = HCF(851,742) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 797 > 1, we apply the division lemma to 797 and 1, to get
797 = 1 x 797 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 797 is 1
Notice that 1 = HCF(797,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 254 > 1, we apply the division lemma to 254 and 1, to get
254 = 1 x 254 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 254 is 1
Notice that 1 = HCF(254,1) .
