HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 369, 106 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 945, 369, 106 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 945, 369, 106 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 945, 369, 106 is 1.
HCF(945, 369, 106) = 1
HCF of 945, 369, 106 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 945, 369, 106 is 1.
Highest Common Factor of 945,369,106 is 1
Step 1: Since 945 > 369, we apply the division lemma to 945 and 369, to get
945 = 369 x 2 + 207
Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 207 and 369, to get
369 = 207 x 1 + 162
Step 3: We consider the new divisor 207 and the new remainder 162, and apply the division lemma to get
207 = 162 x 1 + 45
We consider the new divisor 162 and the new remainder 45,and apply the division lemma to get
162 = 45 x 3 + 27
We consider the new divisor 45 and the new remainder 27,and apply the division lemma to get
45 = 27 x 1 + 18
We consider the new divisor 27 and the new remainder 18,and apply the division lemma to get
27 = 18 x 1 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 945 and 369 is 9
Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(45,27) = HCF(162,45) = HCF(207,162) = HCF(369,207) = HCF(945,369) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 106 > 9, we apply the division lemma to 106 and 9, to get
106 = 9 x 11 + 7
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 7 and 9, to get
9 = 7 x 1 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 1
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 9 and 106 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(106,9) .
