HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 968, 169, 436 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 968, 169, 436 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 968, 169, 436 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 968, 169, 436 is 1.
HCF(968, 169, 436) = 1
HCF of 968, 169, 436 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 968, 169, 436 is 1.
Highest Common Factor of 968,169,436 is 1
Step 1: Since 968 > 169, we apply the division lemma to 968 and 169, to get
968 = 169 x 5 + 123
Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 123 and 169, to get
169 = 123 x 1 + 46
Step 3: We consider the new divisor 123 and the new remainder 46, and apply the division lemma to get
123 = 46 x 2 + 31
We consider the new divisor 46 and the new remainder 31,and apply the division lemma to get
46 = 31 x 1 + 15
We consider the new divisor 31 and the new remainder 15,and apply the division lemma to get
31 = 15 x 2 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 968 and 169 is 1
Notice that 1 = HCF(15,1) = HCF(31,15) = HCF(46,31) = HCF(123,46) = HCF(169,123) = HCF(968,169) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 436 > 1, we apply the division lemma to 436 and 1, to get
436 = 1 x 436 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 436 is 1
Notice that 1 = HCF(436,1) .
