HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 824, 561, 92 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 685, 824, 561, 92 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 685, 824, 561, 92 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 685, 824, 561, 92 is 1.
HCF(685, 824, 561, 92) = 1
HCF of 685, 824, 561, 92 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 685, 824, 561, 92 is 1.
Highest Common Factor of 685,824,561,92 is 1
Step 1: Since 824 > 685, we apply the division lemma to 824 and 685, to get
824 = 685 x 1 + 139
Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 139 and 685, to get
685 = 139 x 4 + 129
Step 3: We consider the new divisor 139 and the new remainder 129, and apply the division lemma to get
139 = 129 x 1 + 10
We consider the new divisor 129 and the new remainder 10,and apply the division lemma to get
129 = 10 x 12 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 685 and 824 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(129,10) = HCF(139,129) = HCF(685,139) = HCF(824,685) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 561 > 1, we apply the division lemma to 561 and 1, to get
561 = 1 x 561 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 561 is 1
Notice that 1 = HCF(561,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 92 > 1, we apply the division lemma to 92 and 1, to get
92 = 1 x 92 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 92 is 1
Notice that 1 = HCF(92,1) .
