GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 441) = 99666
GCD(678, 441) = ( 678 x 441 ) / 99666
= 678 / 441
= 678
Step2:
LCM(3, 497) = 1491
GCD(3, 497) = ( 3 x 497 ) / 1491
= 3 / 497
= 3
Step3:
LCM(1, 425) = 425
GCD(1, 425) = ( 1 x 425 ) / 425
= 1 / 425
= 1
So, Greatest Common Divisor of 678, 441, 497, 425 is 1
