HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 898, 946, 18 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 898, 946, 18 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 975, 898, 946, 18 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 975, 898, 946, 18 is 1.
HCF(975, 898, 946, 18) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 898, 946, 18 is 1.
Step 1: Since 975 > 898, we apply the division lemma to 975 and 898, to get
975 = 898 x 1 + 77
Step 2: Since the reminder 898 ≠ 0, we apply division lemma to 77 and 898, to get
898 = 77 x 11 + 51
Step 3: We consider the new divisor 77 and the new remainder 51, and apply the division lemma to get
77 = 51 x 1 + 26
We consider the new divisor 51 and the new remainder 26,and apply the division lemma to get
51 = 26 x 1 + 25
We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get
26 = 25 x 1 + 1
We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 975 and 898 is 1
Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(51,26) = HCF(77,51) = HCF(898,77) = HCF(975,898) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 946 > 1, we apply the division lemma to 946 and 1, to get
946 = 1 x 946 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 946 is 1
Notice that 1 = HCF(946,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 18 > 1, we apply the division lemma to 18 and 1, to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 18 is 1
Notice that 1 = HCF(18,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
