GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(439, 781) = 342859
GCD(439, 781) = ( 439 x 781 ) / 342859
= 439 / 781
= 439
Step2:
LCM(1, 568) = 568
GCD(1, 568) = ( 1 x 568 ) / 568
= 1 / 568
= 1
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 439, 781, 568, 378 is 1
