HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 663, 175 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 663, 175 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, 663, 175 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, 663, 175 is 1.
HCF(918, 663, 175) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 663, 175 is 1.
Step 1: Since 918 > 663, we apply the division lemma to 918 and 663, to get
918 = 663 x 1 + 255
Step 2: Since the reminder 663 ≠ 0, we apply division lemma to 255 and 663, to get
663 = 255 x 2 + 153
Step 3: We consider the new divisor 255 and the new remainder 153, and apply the division lemma to get
255 = 153 x 1 + 102
We consider the new divisor 153 and the new remainder 102,and apply the division lemma to get
153 = 102 x 1 + 51
We consider the new divisor 102 and the new remainder 51,and apply the division lemma to get
102 = 51 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 51, the HCF of 918 and 663 is 51
Notice that 51 = HCF(102,51) = HCF(153,102) = HCF(255,153) = HCF(663,255) = HCF(918,663) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 175 > 51, we apply the division lemma to 175 and 51, to get
175 = 51 x 3 + 22
Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 22 and 51, to get
51 = 22 x 2 + 7
Step 3: We consider the new divisor 22 and the new remainder 7, and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 51 and 175 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(51,22) = HCF(175,51) .
Here are some samples of HCF using Euclid's Algorithm calculations.
