Given numbers are 308, 778, 621, 424
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 778) = 119812
GCD(308, 778) = ( 308 x 778 ) / 119812
= 308 / 778
= 308
Step2:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
Step3:
LCM(1, 424) = 424
GCD(1, 424) = ( 1 x 424 ) / 424
= 1 / 424
= 1
So, Greatest Common Divisor of 308, 778, 621, 424 is 1
