Given numbers are 411, 970, 509, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(411, 970) = 398670
GCD(411, 970) = ( 411 x 970 ) / 398670
= 411 / 970
= 411
Step2:
LCM(1, 509) = 509
GCD(1, 509) = ( 1 x 509 ) / 509
= 1 / 509
= 1
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 411, 970, 509, 778 is 1
