HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 422, 435 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 422, 435 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 625, 422, 435 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 625, 422, 435 is 1.
HCF(625, 422, 435) = 1
HCF of 625, 422, 435 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 625, 422, 435 is 1.
Highest Common Factor of 625,422,435 is 1
Step 1: Since 625 > 422, we apply the division lemma to 625 and 422, to get
625 = 422 x 1 + 203
Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 203 and 422, to get
422 = 203 x 2 + 16
Step 3: We consider the new divisor 203 and the new remainder 16, and apply the division lemma to get
203 = 16 x 12 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 625 and 422 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(203,16) = HCF(422,203) = HCF(625,422) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 435 > 1, we apply the division lemma to 435 and 1, to get
435 = 1 x 435 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 435 is 1
Notice that 1 = HCF(435,1) .
