HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 87930 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 87930 is 18 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, 87930 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, 87930 is 18.
HCF(918, 87930) = 18
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 87930 is 18.
Step 1: Since 87930 > 918, we apply the division lemma to 87930 and 918, to get
87930 = 918 x 95 + 720
Step 2: Since the reminder 918 ≠ 0, we apply division lemma to 720 and 918, to get
918 = 720 x 1 + 198
Step 3: We consider the new divisor 720 and the new remainder 198, and apply the division lemma to get
720 = 198 x 3 + 126
We consider the new divisor 198 and the new remainder 126,and apply the division lemma to get
198 = 126 x 1 + 72
We consider the new divisor 126 and the new remainder 72,and apply the division lemma to get
126 = 72 x 1 + 54
We consider the new divisor 72 and the new remainder 54,and apply the division lemma to get
72 = 54 x 1 + 18
We consider the new divisor 54 and the new remainder 18,and apply the division lemma to get
54 = 18 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 918 and 87930 is 18
Notice that 18 = HCF(54,18) = HCF(72,54) = HCF(126,72) = HCF(198,126) = HCF(720,198) = HCF(918,720) = HCF(87930,918) .
Here are some samples of HCF using Euclid's Algorithm calculations.
