Given numbers are 978, 677, 642, 262
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 677) = 662106
GCD(978, 677) = ( 978 x 677 ) / 662106
= 978 / 677
= 978
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 262) = 262
GCD(1, 262) = ( 1 x 262 ) / 262
= 1 / 262
= 1
So, Greatest Common Divisor of 978, 677, 642, 262 is 1
