Given numbers are 420, 802, 186, 579
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 802) = 168420
GCD(420, 802) = ( 420 x 802 ) / 168420
= 420 / 802
= 420
Step2:
LCM(2, 186) = 186
GCD(2, 186) = ( 2 x 186 ) / 186
= 2 / 186
= 2
Step3:
LCM(2, 579) = 1158
GCD(2, 579) = ( 2 x 579 ) / 1158
= 2 / 579
= 2
So, Greatest Common Divisor of 420, 802, 186, 579 is 1
