HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 420, 708, 244 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 420, 708, 244 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 420, 708, 244 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 420, 708, 244 is 4.
HCF(420, 708, 244) = 4
HCF of 420, 708, 244 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 420, 708, 244 is 4.
Highest Common Factor of 420,708,244 is 4
Step 1: Since 708 > 420, we apply the division lemma to 708 and 420, to get
708 = 420 x 1 + 288
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 288 and 420, to get
420 = 288 x 1 + 132
Step 3: We consider the new divisor 288 and the new remainder 132, and apply the division lemma to get
288 = 132 x 2 + 24
We consider the new divisor 132 and the new remainder 24,and apply the division lemma to get
132 = 24 x 5 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 420 and 708 is 12
Notice that 12 = HCF(24,12) = HCF(132,24) = HCF(288,132) = HCF(420,288) = HCF(708,420) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 244 > 12, we apply the division lemma to 244 and 12, to get
244 = 12 x 20 + 4
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 4 and 12, 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 12 and 244 is 4
Notice that 4 = HCF(12,4) = HCF(244,12) .
