HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 841, 688, 959, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 841, 688, 959, 28 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 841, 688, 959, 28 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 841, 688, 959, 28 is 1.
HCF(841, 688, 959, 28) = 1
HCF of 841, 688, 959, 28 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 841, 688, 959, 28 is 1.
Highest Common Factor of 841,688,959,28 is 1
Step 1: Since 841 > 688, we apply the division lemma to 841 and 688, to get
841 = 688 x 1 + 153
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 153 and 688, to get
688 = 153 x 4 + 76
Step 3: We consider the new divisor 153 and the new remainder 76, and apply the division lemma to get
153 = 76 x 2 + 1
We consider the new divisor 76 and the new remainder 1, and apply the division lemma to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 841 and 688 is 1
Notice that 1 = HCF(76,1) = HCF(153,76) = HCF(688,153) = HCF(841,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 959 > 1, we apply the division lemma to 959 and 1, to get
959 = 1 x 959 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 959 is 1
Notice that 1 = HCF(959,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1
Notice that 1 = HCF(28,1) .
