HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 924, 400 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 84, 924, 400 is 4 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 84, 924, 400 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 84, 924, 400 is 4.
HCF(84, 924, 400) = 4
HCF of 84, 924, 400 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 84, 924, 400 is 4.
Highest Common Factor of 84,924,400 is 4
Step 1: Since 924 > 84, we apply the division lemma to 924 and 84, to get
924 = 84 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 84, the HCF of 84 and 924 is 84
Notice that 84 = HCF(924,84) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 400 > 84, we apply the division lemma to 400 and 84, to get
400 = 84 x 4 + 64
Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 64 and 84, to get
84 = 64 x 1 + 20
Step 3: We consider the new divisor 64 and the new remainder 20, and apply the division lemma to get
64 = 20 x 3 + 4
We consider the new divisor 20 and the new remainder 4, and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 84 and 400 is 4
Notice that 4 = HCF(20,4) = HCF(64,20) = HCF(84,64) = HCF(400,84) .
