HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 606, 955, 78, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 606, 955, 78, 485 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 606, 955, 78, 485 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 606, 955, 78, 485 is 1.
HCF(606, 955, 78, 485) = 1
HCF of 606, 955, 78, 485 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 606, 955, 78, 485 is 1.
Highest Common Factor of 606,955,78,485 is 1
Step 1: Since 955 > 606, we apply the division lemma to 955 and 606, to get
955 = 606 x 1 + 349
Step 2: Since the reminder 606 ≠ 0, we apply division lemma to 349 and 606, to get
606 = 349 x 1 + 257
Step 3: We consider the new divisor 349 and the new remainder 257, and apply the division lemma to get
349 = 257 x 1 + 92
We consider the new divisor 257 and the new remainder 92,and apply the division lemma to get
257 = 92 x 2 + 73
We consider the new divisor 92 and the new remainder 73,and apply the division lemma to get
92 = 73 x 1 + 19
We consider the new divisor 73 and the new remainder 19,and apply the division lemma to get
73 = 19 x 3 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
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 606 and 955 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(73,19) = HCF(92,73) = HCF(257,92) = HCF(349,257) = HCF(606,349) = HCF(955,606) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 485 > 1, we apply the division lemma to 485 and 1, to get
485 = 1 x 485 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 485 is 1
Notice that 1 = HCF(485,1) .
