Given numbers are 399, 572, 665, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 572) = 228228
GCD(399, 572) = ( 399 x 572 ) / 228228
= 399 / 572
= 399
Step2:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 399, 572, 665, 770 is 1
