HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 28, 360, 824 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 68, 28, 360, 824 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 68, 28, 360, 824 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 68, 28, 360, 824 is 4.
HCF(68, 28, 360, 824) = 4
HCF of 68, 28, 360, 824 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 68, 28, 360, 824 is 4.
Highest Common Factor of 68,28,360,824 is 4
Step 1: Since 68 > 28, we apply the division lemma to 68 and 28, to get
68 = 28 x 2 + 12
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 12 and 28, to get
28 = 12 x 2 + 4
Step 3: We consider the new divisor 12 and the new remainder 4, and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 68 and 28 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(68,28) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 360 > 4, we apply the division lemma to 360 and 4, to get
360 = 4 x 90 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 360 is 4
Notice that 4 = HCF(360,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 824 > 4, we apply the division lemma to 824 and 4, to get
824 = 4 x 206 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 824 is 4
Notice that 4 = HCF(824,4) .
