Given numbers are 666, 639, 290, 570
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 639) = 47286
GCD(666, 639) = ( 666 x 639 ) / 47286
= 666 / 639
= 666
Step2:
LCM(9, 290) = 2610
GCD(9, 290) = ( 9 x 290 ) / 2610
= 9 / 290
= 9
Step3:
LCM(1, 570) = 570
GCD(1, 570) = ( 1 x 570 ) / 570
= 1 / 570
= 1
So, Greatest Common Divisor of 666, 639, 290, 570 is 1
