Given numbers are 618, 424, 340, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 424) = 131016
GCD(618, 424) = ( 618 x 424 ) / 131016
= 618 / 424
= 618
Step2:
LCM(2, 340) = 340
GCD(2, 340) = ( 2 x 340 ) / 340
= 2 / 340
= 2
Step3:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
So, Greatest Common Divisor of 618, 424, 340, 621 is 1
