Given numbers are 383, 568, 409, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(383, 568) = 217544
GCD(383, 568) = ( 383 x 568 ) / 217544
= 383 / 568
= 383
Step2:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 383, 568, 409, 642 is 1
