HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 430, 858, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 430, 858, 225 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 430, 858, 225 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 430, 858, 225 is 1.
HCF(430, 858, 225) = 1
HCF of 430, 858, 225 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 430, 858, 225 is 1.
Highest Common Factor of 430,858,225 is 1
Step 1: Since 858 > 430, we apply the division lemma to 858 and 430, to get
858 = 430 x 1 + 428
Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 428 and 430, to get
430 = 428 x 1 + 2
Step 3: We consider the new divisor 428 and the new remainder 2, and apply the division lemma to get
428 = 2 x 214 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 430 and 858 is 2
Notice that 2 = HCF(428,2) = HCF(430,428) = HCF(858,430) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 225 > 2, we apply the division lemma to 225 and 2, to get
225 = 2 x 112 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 225 is 1
Notice that 1 = HCF(2,1) = HCF(225,2) .
