HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 360, 849 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 424, 360, 849 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 424, 360, 849 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 424, 360, 849 is 1.
HCF(424, 360, 849) = 1
HCF of 424, 360, 849 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 424, 360, 849 is 1.
Highest Common Factor of 424,360,849 is 1
Step 1: Since 424 > 360, we apply the division lemma to 424 and 360, to get
424 = 360 x 1 + 64
Step 2: Since the reminder 360 ≠ 0, we apply division lemma to 64 and 360, to get
360 = 64 x 5 + 40
Step 3: We consider the new divisor 64 and the new remainder 40, and apply the division lemma to get
64 = 40 x 1 + 24
We consider the new divisor 40 and the new remainder 24,and apply the division lemma to get
40 = 24 x 1 + 16
We consider the new divisor 24 and the new remainder 16,and apply the division lemma to get
24 = 16 x 1 + 8
We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 424 and 360 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) = HCF(64,40) = HCF(360,64) = HCF(424,360) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 849 > 8, we apply the division lemma to 849 and 8, to get
849 = 8 x 106 + 1
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 1 and 8, to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 849 is 1
Notice that 1 = HCF(8,1) = HCF(849,8) .
