HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 639, 687, 936 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 454, 639, 687, 936 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 454, 639, 687, 936 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 454, 639, 687, 936 is 1.
HCF(454, 639, 687, 936) = 1
HCF of 454, 639, 687, 936 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 454, 639, 687, 936 is 1.
Highest Common Factor of 454,639,687,936 is 1
Step 1: Since 639 > 454, we apply the division lemma to 639 and 454, to get
639 = 454 x 1 + 185
Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 185 and 454, to get
454 = 185 x 2 + 84
Step 3: We consider the new divisor 185 and the new remainder 84, and apply the division lemma to get
185 = 84 x 2 + 17
We consider the new divisor 84 and the new remainder 17,and apply the division lemma to get
84 = 17 x 4 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 454 and 639 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(84,17) = HCF(185,84) = HCF(454,185) = HCF(639,454) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 687 > 1, we apply the division lemma to 687 and 1, to get
687 = 1 x 687 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 687 is 1
Notice that 1 = HCF(687,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 936 > 1, we apply the division lemma to 936 and 1, to get
936 = 1 x 936 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 936 is 1
Notice that 1 = HCF(936,1) .
