Given numbers are 284, 620, 694, 213
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(284, 620) = 44020
GCD(284, 620) = ( 284 x 620 ) / 44020
= 284 / 620
= 284
Step2:
LCM(4, 694) = 1388
GCD(4, 694) = ( 4 x 694 ) / 1388
= 4 / 694
= 4
Step3:
LCM(2, 213) = 426
GCD(2, 213) = ( 2 x 213 ) / 426
= 2 / 213
= 2
So, Greatest Common Divisor of 284, 620, 694, 213 is 1
