HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 700, 180, 256, 635 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 700, 180, 256, 635 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 700, 180, 256, 635 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 700, 180, 256, 635 is 1.
HCF(700, 180, 256, 635) = 1
HCF of 700, 180, 256, 635 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 700, 180, 256, 635 is 1.
Highest Common Factor of 700,180,256,635 is 1
Step 1: Since 700 > 180, we apply the division lemma to 700 and 180, to get
700 = 180 x 3 + 160
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 160 and 180, to get
180 = 160 x 1 + 20
Step 3: We consider the new divisor 160 and the new remainder 20, and apply the division lemma to get
160 = 20 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 700 and 180 is 20
Notice that 20 = HCF(160,20) = HCF(180,160) = HCF(700,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 256 > 20, we apply the division lemma to 256 and 20, to get
256 = 20 x 12 + 16
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 16 and 20, to get
20 = 16 x 1 + 4
Step 3: We consider the new divisor 16 and the new remainder 4, and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 20 and 256 is 4
Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(256,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 635 > 4, we apply the division lemma to 635 and 4, to get
635 = 4 x 158 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 635 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(635,4) .
