Given numbers are 640, 970, 859, 580
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 970) = 62080
GCD(640, 970) = ( 640 x 970 ) / 62080
= 640 / 970
= 640
Step2:
LCM(10, 859) = 8590
GCD(10, 859) = ( 10 x 859 ) / 8590
= 10 / 859
= 10
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 640, 970, 859, 580 is 1
