HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 905, 377, 52 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 905, 377, 52 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 505, 905, 377, 52 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 505, 905, 377, 52 is 1.
HCF(505, 905, 377, 52) = 1
HCF of 505, 905, 377, 52 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 905, 377, 52 is 1.
Highest Common Factor of 505,905,377,52 is 1
Step 1: Since 905 > 505, we apply the division lemma to 905 and 505, to get
905 = 505 x 1 + 400
Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 400 and 505, to get
505 = 400 x 1 + 105
Step 3: We consider the new divisor 400 and the new remainder 105, and apply the division lemma to get
400 = 105 x 3 + 85
We consider the new divisor 105 and the new remainder 85,and apply the division lemma to get
105 = 85 x 1 + 20
We consider the new divisor 85 and the new remainder 20,and apply the division lemma to get
85 = 20 x 4 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 505 and 905 is 5
Notice that 5 = HCF(20,5) = HCF(85,20) = HCF(105,85) = HCF(400,105) = HCF(505,400) = HCF(905,505) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 377 > 5, we apply the division lemma to 377 and 5, to get
377 = 5 x 75 + 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 377 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(377,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 52 > 1, we apply the division lemma to 52 and 1, to get
52 = 1 x 52 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 52 is 1
Notice that 1 = HCF(52,1) .
