HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 164, 865, 328, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 164, 865, 328, 947 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 164, 865, 328, 947 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 164, 865, 328, 947 is 1.
HCF(164, 865, 328, 947) = 1
HCF of 164, 865, 328, 947 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 164, 865, 328, 947 is 1.
Highest Common Factor of 164,865,328,947 is 1
Step 1: Since 865 > 164, we apply the division lemma to 865 and 164, to get
865 = 164 x 5 + 45
Step 2: Since the reminder 164 ≠ 0, we apply division lemma to 45 and 164, to get
164 = 45 x 3 + 29
Step 3: We consider the new divisor 45 and the new remainder 29, and apply the division lemma to get
45 = 29 x 1 + 16
We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get
29 = 16 x 1 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 164 and 865 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(45,29) = HCF(164,45) = HCF(865,164) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 328 > 1, we apply the division lemma to 328 and 1, to get
328 = 1 x 328 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 328 is 1
Notice that 1 = HCF(328,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 947 > 1, we apply the division lemma to 947 and 1, to get
947 = 1 x 947 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 947 is 1
Notice that 1 = HCF(947,1) .
