Given numbers are 400, 642, 26, 533
The list of prime factors of all numbers are
Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5
Prime factors of 642 are 2 x 3 x 107
Prime factors of 26 are 2 x 13
Prime factors of 533 are 13 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 400, 642, 26, 533
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 642) = 128400
GCD(400, 642) = ( 400 x 642 ) / 128400
= 400 / 642
= 400
Step2:
LCM(2, 26) = 26
GCD(2, 26) = ( 2 x 26 ) / 26
= 2 / 26
= 2
Step3:
LCM(2, 533) = 1066
GCD(2, 533) = ( 2 x 533 ) / 1066
= 2 / 533
= 2
So, Greatest Common Divisor of 400, 642, 26, 533 is 1
