Given numbers are 386, 342, 609, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 342) = 66006
GCD(386, 342) = ( 386 x 342 ) / 66006
= 386 / 342
= 386
Step2:
LCM(2, 609) = 1218
GCD(2, 609) = ( 2 x 609 ) / 1218
= 2 / 609
= 2
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 386, 342, 609, 520 is 1
