HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 692, 630 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 692, 630 is 2 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 432, 692, 630 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 432, 692, 630 is 2.
HCF(432, 692, 630) = 2
HCF of 432, 692, 630 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 692, 630 is 2.
Highest Common Factor of 432,692,630 is 2
Step 1: Since 692 > 432, we apply the division lemma to 692 and 432, to get
692 = 432 x 1 + 260
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 260 and 432, to get
432 = 260 x 1 + 172
Step 3: We consider the new divisor 260 and the new remainder 172, and apply the division lemma to get
260 = 172 x 1 + 88
We consider the new divisor 172 and the new remainder 88,and apply the division lemma to get
172 = 88 x 1 + 84
We consider the new divisor 88 and the new remainder 84,and apply the division lemma to get
88 = 84 x 1 + 4
We consider the new divisor 84 and the new remainder 4,and apply the division lemma to get
84 = 4 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 432 and 692 is 4
Notice that 4 = HCF(84,4) = HCF(88,84) = HCF(172,88) = HCF(260,172) = HCF(432,260) = HCF(692,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 630 > 4, we apply the division lemma to 630 and 4, to get
630 = 4 x 157 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 630 is 2
Notice that 2 = HCF(4,2) = HCF(630,4) .
