Prime factors of 402 are 2 x 3 x 67
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 406, 421, 535, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 421) = 170926
GCD(406, 421) = ( 406 x 421 ) / 170926
= 406 / 421
= 406
Step2:
LCM(1, 535) = 535
GCD(1, 535) = ( 1 x 535 ) / 535
= 1 / 535
= 1
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 406, 421, 535, 402 is 1
