Given numbers are 474, 780, 699, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(474, 780) = 61620
GCD(474, 780) = ( 474 x 780 ) / 61620
= 474 / 780
= 474
Step2:
LCM(6, 699) = 1398
GCD(6, 699) = ( 6 x 699 ) / 1398
= 6 / 699
= 6
Step3:
LCM(3, 647) = 1941
GCD(3, 647) = ( 3 x 647 ) / 1941
= 3 / 647
= 3
So, Greatest Common Divisor of 474, 780, 699, 647 is 1
