HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 475, 280, 136 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 475, 280, 136 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 475, 280, 136 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 475, 280, 136 is 1.
HCF(475, 280, 136) = 1
HCF of 475, 280, 136 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 475, 280, 136 is 1.
Highest Common Factor of 475,280,136 is 1
Step 1: Since 475 > 280, we apply the division lemma to 475 and 280, to get
475 = 280 x 1 + 195
Step 2: Since the reminder 280 ≠ 0, we apply division lemma to 195 and 280, to get
280 = 195 x 1 + 85
Step 3: We consider the new divisor 195 and the new remainder 85, and apply the division lemma to get
195 = 85 x 2 + 25
We consider the new divisor 85 and the new remainder 25,and apply the division lemma to get
85 = 25 x 3 + 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 475 and 280 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(85,25) = HCF(195,85) = HCF(280,195) = HCF(475,280) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 136 > 5, we apply the division lemma to 136 and 5, to get
136 = 5 x 27 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 136 is 1
Notice that 1 = HCF(5,1) = HCF(136,5) .
