GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 864) = 66528
GCD(308, 864) = ( 308 x 864 ) / 66528
= 308 / 864
= 308
Step2:
LCM(4, 540) = 540
GCD(4, 540) = ( 4 x 540 ) / 540
= 4 / 540
= 4
Step3:
LCM(4, 642) = 1284
GCD(4, 642) = ( 4 x 642 ) / 1284
= 4 / 642
= 4
So, Greatest Common Divisor of 308, 864, 540, 642 is 2
