GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 715) = 306020
GCD(428, 715) = ( 428 x 715 ) / 306020
= 428 / 715
= 428
Step2:
LCM(1, 474) = 474
GCD(1, 474) = ( 1 x 474 ) / 474
= 1 / 474
= 1
Step3:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
So, Greatest Common Divisor of 428, 715, 474, 978 is 1
