HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 250, 905, 140, 277 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 250, 905, 140, 277 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 250, 905, 140, 277 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 250, 905, 140, 277 is 1.
HCF(250, 905, 140, 277) = 1
HCF of 250, 905, 140, 277 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 250, 905, 140, 277 is 1.
Highest Common Factor of 250,905,140,277 is 1
Step 1: Since 905 > 250, we apply the division lemma to 905 and 250, to get
905 = 250 x 3 + 155
Step 2: Since the reminder 250 ≠ 0, we apply division lemma to 155 and 250, to get
250 = 155 x 1 + 95
Step 3: We consider the new divisor 155 and the new remainder 95, and apply the division lemma to get
155 = 95 x 1 + 60
We consider the new divisor 95 and the new remainder 60,and apply the division lemma to get
95 = 60 x 1 + 35
We consider the new divisor 60 and the new remainder 35,and apply the division lemma to get
60 = 35 x 1 + 25
We consider the new divisor 35 and the new remainder 25,and apply the division lemma to get
35 = 25 x 1 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 250 and 905 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(35,25) = HCF(60,35) = HCF(95,60) = HCF(155,95) = HCF(250,155) = HCF(905,250) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 140 > 5, we apply the division lemma to 140 and 5, to get
140 = 5 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 140 is 5
Notice that 5 = HCF(140,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 277 > 5, we apply the division lemma to 277 and 5, to get
277 = 5 x 55 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 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 5 and 277 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(277,5) .
