Given numbers are 698, 746, 615, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(698, 746) = 260354
GCD(698, 746) = ( 698 x 746 ) / 260354
= 698 / 746
= 698
Step2:
LCM(2, 615) = 1230
GCD(2, 615) = ( 2 x 615 ) / 1230
= 2 / 615
= 2
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 698, 746, 615, 520 is 1
