HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 9895, 7453 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 9895, 7453 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, 9895, 7453 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, 9895, 7453 is 1.
HCF(918, 9895, 7453) = 1
HCF of 918, 9895, 7453 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, 9895, 7453 is 1.
Highest Common Factor of 918,9895,7453 is 1
Step 1: Since 9895 > 918, we apply the division lemma to 9895 and 918, to get
9895 = 918 x 10 + 715
Step 2: Since the reminder 918 ≠ 0, we apply division lemma to 715 and 918, to get
918 = 715 x 1 + 203
Step 3: We consider the new divisor 715 and the new remainder 203, and apply the division lemma to get
715 = 203 x 3 + 106
We consider the new divisor 203 and the new remainder 106,and apply the division lemma to get
203 = 106 x 1 + 97
We consider the new divisor 106 and the new remainder 97,and apply the division lemma to get
106 = 97 x 1 + 9
We consider the new divisor 97 and the new remainder 9,and apply the division lemma to get
97 = 9 x 10 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
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 918 and 9895 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(97,9) = HCF(106,97) = HCF(203,106) = HCF(715,203) = HCF(918,715) = HCF(9895,918) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 7453 > 1, we apply the division lemma to 7453 and 1, to get
7453 = 1 x 7453 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7453 is 1
Notice that 1 = HCF(7453,1) .
