HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 207, 941, 686, 685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 207, 941, 686, 685 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 207, 941, 686, 685 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 207, 941, 686, 685 is 1.
HCF(207, 941, 686, 685) = 1
HCF of 207, 941, 686, 685 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 207, 941, 686, 685 is 1.
Highest Common Factor of 207,941,686,685 is 1
Step 1: Since 941 > 207, we apply the division lemma to 941 and 207, to get
941 = 207 x 4 + 113
Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 113 and 207, to get
207 = 113 x 1 + 94
Step 3: We consider the new divisor 113 and the new remainder 94, and apply the division lemma to get
113 = 94 x 1 + 19
We consider the new divisor 94 and the new remainder 19,and apply the division lemma to get
94 = 19 x 4 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 207 and 941 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(94,19) = HCF(113,94) = HCF(207,113) = HCF(941,207) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 686 > 1, we apply the division lemma to 686 and 1, to get
686 = 1 x 686 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 686 is 1
Notice that 1 = HCF(686,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 685 > 1, we apply the division lemma to 685 and 1, to get
685 = 1 x 685 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 685 is 1
Notice that 1 = HCF(685,1) .
