Given numbers are 430, 492, 669, 742
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 492) = 105780
GCD(430, 492) = ( 430 x 492 ) / 105780
= 430 / 492
= 430
Step2:
LCM(2, 669) = 1338
GCD(2, 669) = ( 2 x 669 ) / 1338
= 2 / 669
= 2
Step3:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
So, Greatest Common Divisor of 430, 492, 669, 742 is 1
