Given numbers are 970, 780, 345, 378
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(970, 780) = 75660
GCD(970, 780) = ( 970 x 780 ) / 75660
= 970 / 780
= 970
Step2:
LCM(10, 345) = 690
GCD(10, 345) = ( 10 x 345 ) / 690
= 10 / 345
= 10
Step3:
LCM(5, 378) = 1890
GCD(5, 378) = ( 5 x 378 ) / 1890
= 5 / 378
= 5
So, Greatest Common Divisor of 970, 780, 345, 378 is 1
