HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 218, 957, 432 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 218, 957, 432 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 218, 957, 432 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 218, 957, 432 is 1.
HCF(218, 957, 432) = 1
HCF of 218, 957, 432 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 218, 957, 432 is 1.
Highest Common Factor of 218,957,432 is 1
Step 1: Since 957 > 218, we apply the division lemma to 957 and 218, to get
957 = 218 x 4 + 85
Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 85 and 218, to get
218 = 85 x 2 + 48
Step 3: We consider the new divisor 85 and the new remainder 48, and apply the division lemma to get
85 = 48 x 1 + 37
We consider the new divisor 48 and the new remainder 37,and apply the division lemma to get
48 = 37 x 1 + 11
We consider the new divisor 37 and the new remainder 11,and apply the division lemma to get
37 = 11 x 3 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 218 and 957 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(37,11) = HCF(48,37) = HCF(85,48) = HCF(218,85) = HCF(957,218) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 432 > 1, we apply the division lemma to 432 and 1, to get
432 = 1 x 432 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 432 is 1
Notice that 1 = HCF(432,1) .
