HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 2945 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 2945 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 918, 2945 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 918, 2945 is 1.
HCF(918, 2945) = 1
HCF of 918, 2945 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 2945 is 1.
Highest Common Factor of 918,2945 is 1
Step 1: Since 2945 > 918, we apply the division lemma to 2945 and 918, to get
2945 = 918 x 3 + 191
Step 2: Since the reminder 918 ≠ 0, we apply division lemma to 191 and 918, to get
918 = 191 x 4 + 154
Step 3: We consider the new divisor 191 and the new remainder 154, and apply the division lemma to get
191 = 154 x 1 + 37
We consider the new divisor 154 and the new remainder 37,and apply the division lemma to get
154 = 37 x 4 + 6
We consider the new divisor 37 and the new remainder 6,and apply the division lemma to get
37 = 6 x 6 + 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 918 and 2945 is 1
Notice that 1 = HCF(6,1) = HCF(37,6) = HCF(154,37) = HCF(191,154) = HCF(918,191) = HCF(2945,918) .
