HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 924, 717 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 924, 717 is 3 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 630, 924, 717 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 630, 924, 717 is 3.
HCF(630, 924, 717) = 3
HCF of 630, 924, 717 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 924, 717 is 3.
Highest Common Factor of 630,924,717 is 3
Step 1: Since 924 > 630, we apply the division lemma to 924 and 630, to get
924 = 630 x 1 + 294
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 294 and 630, to get
630 = 294 x 2 + 42
Step 3: We consider the new divisor 294 and the new remainder 42, and apply the division lemma to get
294 = 42 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 42, the HCF of 630 and 924 is 42
Notice that 42 = HCF(294,42) = HCF(630,294) = HCF(924,630) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 717 > 42, we apply the division lemma to 717 and 42, to get
717 = 42 x 17 + 3
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 3 and 42, to get
42 = 3 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 42 and 717 is 3
Notice that 3 = HCF(42,3) = HCF(717,42) .
