Given numbers are 409, 570, 346, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 570) = 233130
GCD(409, 570) = ( 409 x 570 ) / 233130
= 409 / 570
= 409
Step2:
LCM(1, 346) = 346
GCD(1, 346) = ( 1 x 346 ) / 346
= 1 / 346
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 409, 570, 346, 642 is 1
