GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 945) = 6615
GCD(245, 945) = ( 245 x 945 ) / 6615
= 245 / 945
= 245
Step2:
LCM(35, 757) = 26495
GCD(35, 757) = ( 35 x 757 ) / 26495
= 35 / 757
= 35
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 245, 945, 757, 630 is 1
