Given numbers are 840, 808, 432, 435
The list of prime factors of all numbers are
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 808 are 2 x 2 x 2 x 101
Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime factors of 435 are 3 x 5 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 808, 432, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 808) = 84840
GCD(840, 808) = ( 840 x 808 ) / 84840
= 840 / 808
= 840
Step2:
LCM(8, 432) = 432
GCD(8, 432) = ( 8 x 432 ) / 432
= 8 / 432
= 8
Step3:
LCM(8, 435) = 3480
GCD(8, 435) = ( 8 x 435 ) / 3480
= 8 / 435
= 8
So, Greatest Common Divisor of 840, 808, 432, 435 is 1
