Given numbers are 620, 284, 195, 695
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 284) = 44020
GCD(620, 284) = ( 620 x 284 ) / 44020
= 620 / 284
= 620
Step2:
LCM(4, 195) = 780
GCD(4, 195) = ( 4 x 195 ) / 780
= 4 / 195
= 4
Step3:
LCM(1, 695) = 695
GCD(1, 695) = ( 1 x 695 ) / 695
= 1 / 695
= 1
So, Greatest Common Divisor of 620, 284, 195, 695 is 1
