Given numbers are 605, 620, 284, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 620) = 75020
GCD(605, 620) = ( 605 x 620 ) / 75020
= 605 / 620
= 605
Step2:
LCM(5, 284) = 1420
GCD(5, 284) = ( 5 x 284 ) / 1420
= 5 / 284
= 5
Step3:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 605, 620, 284, 402 is 1
