Given numbers are 386, 506, 942, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 506) = 97658
GCD(386, 506) = ( 386 x 506 ) / 97658
= 386 / 506
= 386
Step2:
LCM(2, 942) = 942
GCD(2, 942) = ( 2 x 942 ) / 942
= 2 / 942
= 2
Step3:
LCM(2, 643) = 1286
GCD(2, 643) = ( 2 x 643 ) / 1286
= 2 / 643
= 2
So, Greatest Common Divisor of 386, 506, 942, 643 is 1
