HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 698, 141, 727 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 251, 698, 141, 727 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 251, 698, 141, 727 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 251, 698, 141, 727 is 1.
HCF(251, 698, 141, 727) = 1
HCF of 251, 698, 141, 727 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 251, 698, 141, 727 is 1.
Highest Common Factor of 251,698,141,727 is 1
Step 1: Since 698 > 251, we apply the division lemma to 698 and 251, to get
698 = 251 x 2 + 196
Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 196 and 251, to get
251 = 196 x 1 + 55
Step 3: We consider the new divisor 196 and the new remainder 55, and apply the division lemma to get
196 = 55 x 3 + 31
We consider the new divisor 55 and the new remainder 31,and apply the division lemma to get
55 = 31 x 1 + 24
We consider the new divisor 31 and the new remainder 24,and apply the division lemma to get
31 = 24 x 1 + 7
We consider the new divisor 24 and the new remainder 7,and apply the division lemma to get
24 = 7 x 3 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 251 and 698 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(24,7) = HCF(31,24) = HCF(55,31) = HCF(196,55) = HCF(251,196) = HCF(698,251) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 141 > 1, we apply the division lemma to 141 and 1, to get
141 = 1 x 141 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 141 is 1
Notice that 1 = HCF(141,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 727 > 1, we apply the division lemma to 727 and 1, to get
727 = 1 x 727 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 727 is 1
Notice that 1 = HCF(727,1) .
