HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 659, 394, 724 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 407, 659, 394, 724 is 1 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 407, 659, 394, 724 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 407, 659, 394, 724 is 1.
HCF(407, 659, 394, 724) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 407, 659, 394, 724 is 1.
Step 1: Since 659 > 407, we apply the division lemma to 659 and 407, to get
659 = 407 x 1 + 252
Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 252 and 407, to get
407 = 252 x 1 + 155
Step 3: We consider the new divisor 252 and the new remainder 155, and apply the division lemma to get
252 = 155 x 1 + 97
We consider the new divisor 155 and the new remainder 97,and apply the division lemma to get
155 = 97 x 1 + 58
We consider the new divisor 97 and the new remainder 58,and apply the division lemma to get
97 = 58 x 1 + 39
We consider the new divisor 58 and the new remainder 39,and apply the division lemma to get
58 = 39 x 1 + 19
We consider the new divisor 39 and the new remainder 19,and apply the division lemma to get
39 = 19 x 2 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 407 and 659 is 1
Notice that 1 = HCF(19,1) = HCF(39,19) = HCF(58,39) = HCF(97,58) = HCF(155,97) = HCF(252,155) = HCF(407,252) = HCF(659,407) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get
394 = 1 x 394 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1
Notice that 1 = HCF(394,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 724 > 1, we apply the division lemma to 724 and 1, to get
724 = 1 x 724 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 724 is 1
Notice that 1 = HCF(724,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
