HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 977, 459, 426, 959 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 977, 459, 426, 959 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 977, 459, 426, 959 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 977, 459, 426, 959 is 1.
HCF(977, 459, 426, 959) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 977, 459, 426, 959 is 1.
Step 1: Since 977 > 459, we apply the division lemma to 977 and 459, to get
977 = 459 x 2 + 59
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 59 and 459, to get
459 = 59 x 7 + 46
Step 3: We consider the new divisor 59 and the new remainder 46, and apply the division lemma to get
59 = 46 x 1 + 13
We consider the new divisor 46 and the new remainder 13,and apply the division lemma to get
46 = 13 x 3 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 977 and 459 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(46,13) = HCF(59,46) = HCF(459,59) = HCF(977,459) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 426 > 1, we apply the division lemma to 426 and 1, to get
426 = 1 x 426 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 426 is 1
Notice that 1 = HCF(426,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 959 > 1, we apply the division lemma to 959 and 1, to get
959 = 1 x 959 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 959 is 1
Notice that 1 = HCF(959,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
