Given numbers are 514, 490, 342, 745
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(514, 490) = 125930
GCD(514, 490) = ( 514 x 490 ) / 125930
= 514 / 490
= 514
Step2:
LCM(2, 342) = 342
GCD(2, 342) = ( 2 x 342 ) / 342
= 2 / 342
= 2
Step3:
LCM(2, 745) = 1490
GCD(2, 745) = ( 2 x 745 ) / 1490
= 2 / 745
= 2
So, Greatest Common Divisor of 514, 490, 342, 745 is 1
