HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 902, 417, 369 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 902, 417, 369 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 649, 902, 417, 369 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 649, 902, 417, 369 is 1.
HCF(649, 902, 417, 369) = 1
HCF of 649, 902, 417, 369 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 649, 902, 417, 369 is 1.
Highest Common Factor of 649,902,417,369 is 1
Step 1: Since 902 > 649, we apply the division lemma to 902 and 649, to get
902 = 649 x 1 + 253
Step 2: Since the reminder 649 ≠ 0, we apply division lemma to 253 and 649, to get
649 = 253 x 2 + 143
Step 3: We consider the new divisor 253 and the new remainder 143, and apply the division lemma to get
253 = 143 x 1 + 110
We consider the new divisor 143 and the new remainder 110,and apply the division lemma to get
143 = 110 x 1 + 33
We consider the new divisor 110 and the new remainder 33,and apply the division lemma to get
110 = 33 x 3 + 11
We consider the new divisor 33 and the new remainder 11,and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 649 and 902 is 11
Notice that 11 = HCF(33,11) = HCF(110,33) = HCF(143,110) = HCF(253,143) = HCF(649,253) = HCF(902,649) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 417 > 11, we apply the division lemma to 417 and 11, to get
417 = 11 x 37 + 10
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 10 and 11, to get
11 = 10 x 1 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 417 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(417,11) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 369 > 1, we apply the division lemma to 369 and 1, to get
369 = 1 x 369 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 369 is 1
Notice that 1 = HCF(369,1) .
