Given numbers are 385, 642, 574, 841
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 642) = 247170
GCD(385, 642) = ( 385 x 642 ) / 247170
= 385 / 642
= 385
Step2:
LCM(1, 574) = 574
GCD(1, 574) = ( 1 x 574 ) / 574
= 1 / 574
= 1
Step3:
LCM(1, 841) = 841
GCD(1, 841) = ( 1 x 841 ) / 841
= 1 / 841
= 1
So, Greatest Common Divisor of 385, 642, 574, 841 is 1
