Given numbers are 521, 780, 977, 282
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 780) = 406380
GCD(521, 780) = ( 521 x 780 ) / 406380
= 521 / 780
= 521
Step2:
LCM(1, 977) = 977
GCD(1, 977) = ( 1 x 977 ) / 977
= 1 / 977
= 1
Step3:
LCM(1, 282) = 282
GCD(1, 282) = ( 1 x 282 ) / 282
= 1 / 282
= 1
So, Greatest Common Divisor of 521, 780, 977, 282 is 1
