HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 477, 892, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 477, 892, 70 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 605, 477, 892, 70 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 605, 477, 892, 70 is 1.
HCF(605, 477, 892, 70) = 1
HCF of 605, 477, 892, 70 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 477, 892, 70 is 1.
Highest Common Factor of 605,477,892,70 is 1
Step 1: Since 605 > 477, we apply the division lemma to 605 and 477, to get
605 = 477 x 1 + 128
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 128 and 477, to get
477 = 128 x 3 + 93
Step 3: We consider the new divisor 128 and the new remainder 93, and apply the division lemma to get
128 = 93 x 1 + 35
We consider the new divisor 93 and the new remainder 35,and apply the division lemma to get
93 = 35 x 2 + 23
We consider the new divisor 35 and the new remainder 23,and apply the division lemma to get
35 = 23 x 1 + 12
We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get
23 = 12 x 1 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 605 and 477 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(35,23) = HCF(93,35) = HCF(128,93) = HCF(477,128) = HCF(605,477) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 892 > 1, we apply the division lemma to 892 and 1, to get
892 = 1 x 892 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 892 is 1
Notice that 1 = HCF(892,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 1, we apply the division lemma to 70 and 1, to get
70 = 1 x 70 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70 is 1
Notice that 1 = HCF(70,1) .
