Given numbers are 640, 390, 524, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 390) = 24960
GCD(640, 390) = ( 640 x 390 ) / 24960
= 640 / 390
= 640
Step2:
LCM(10, 524) = 2620
GCD(10, 524) = ( 10 x 524 ) / 2620
= 10 / 524
= 10
Step3:
LCM(2, 211) = 422
GCD(2, 211) = ( 2 x 211 ) / 422
= 2 / 211
= 2
So, Greatest Common Divisor of 640, 390, 524, 211 is 1
