Given numbers are 420, 535, 649, 446
The list of prime factors of all numbers are
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 535 are 5 x 107
Prime factors of 649 are 11 x 59
Prime factors of 446 are 2 x 223
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 420, 535, 649, 446
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 535) = 44940
GCD(420, 535) = ( 420 x 535 ) / 44940
= 420 / 535
= 420
Step2:
LCM(5, 649) = 3245
GCD(5, 649) = ( 5 x 649 ) / 3245
= 5 / 649
= 5
Step3:
LCM(1, 446) = 446
GCD(1, 446) = ( 1 x 446 ) / 446
= 1 / 446
= 1
So, Greatest Common Divisor of 420, 535, 649, 446 is 1
