HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 288, 762 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 288, 762 is 6 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, 288, 762 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, 288, 762 is 6.
HCF(432, 288, 762) = 6
HCF of 432, 288, 762 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, 288, 762 is 6.
Highest Common Factor of 432,288,762 is 6
Step 1: Since 432 > 288, we apply the division lemma to 432 and 288, to get
432 = 288 x 1 + 144
Step 2: Since the reminder 288 ≠ 0, we apply division lemma to 144 and 288, to get
288 = 144 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 144, the HCF of 432 and 288 is 144
Notice that 144 = HCF(288,144) = HCF(432,288) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 144, we apply the division lemma to 762 and 144, to get
762 = 144 x 5 + 42
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 42 and 144, to get
144 = 42 x 3 + 18
Step 3: We consider the new divisor 42 and the new remainder 18, and apply the division lemma to get
42 = 18 x 2 + 6
We consider the new divisor 18 and the new remainder 6, and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 144 and 762 is 6
Notice that 6 = HCF(18,6) = HCF(42,18) = HCF(144,42) = HCF(762,144) .
