HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 166, 945, 756 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 166, 945, 756 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 166, 945, 756 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 166, 945, 756 is 1.
HCF(166, 945, 756) = 1
HCF of 166, 945, 756 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 166, 945, 756 is 1.
Highest Common Factor of 166,945,756 is 1
Step 1: Since 945 > 166, we apply the division lemma to 945 and 166, to get
945 = 166 x 5 + 115
Step 2: Since the reminder 166 ≠ 0, we apply division lemma to 115 and 166, to get
166 = 115 x 1 + 51
Step 3: We consider the new divisor 115 and the new remainder 51, and apply the division lemma to get
115 = 51 x 2 + 13
We consider the new divisor 51 and the new remainder 13,and apply the division lemma to get
51 = 13 x 3 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 166 and 945 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(51,13) = HCF(115,51) = HCF(166,115) = HCF(945,166) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 756 > 1, we apply the division lemma to 756 and 1, to get
756 = 1 x 756 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 756 is 1
Notice that 1 = HCF(756,1) .
