GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 164) = 40508
GCD(247, 164) = ( 247 x 164 ) / 40508
= 247 / 164
= 247
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 486) = 486
GCD(1, 486) = ( 1 x 486 ) / 486
= 1 / 486
= 1
So, Greatest Common Divisor of 247, 164, 668, 486 is 1
