Given numbers are 874, 342, 405, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(874, 342) = 7866
GCD(874, 342) = ( 874 x 342 ) / 7866
= 874 / 342
= 874
Step2:
LCM(38, 405) = 15390
GCD(38, 405) = ( 38 x 405 ) / 15390
= 38 / 405
= 38
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 874, 342, 405, 490 is 1
